• My new anti-patent BSD-based license: necessary and effective? [closed]

  - by paperjam

  I am writing multimedia software in a domain that is rife with software patents. I want to open source my software but only for the benefit of those who don't play the patent game, that is enthusiasts, small companies, research projects, etc. The idea is, if my code would infringe a software patent somewhere and a company pays to license that patent, they then lose the right to use and distribute my software. Now I detest license proliferation as much as anyone but I can't find an existing OSI approved license that does this. The GPL comes close, but it only restricts distribution, not use. I want to stop someone using my software should they obtain a patent license to do so. Does another license do this job? Is the wording below unambiguous? - I don't want a legal opinion, just whether it would be interpreted as I intend. Copyright (c) <year>, <copyright holder> All rights reserved. Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: [ three standard new-BSD conditions not shown here] * No patents are licensed from any third party in respect of redistribution or use of this software or its derivatives unless the patent license is arranged to permit free use and distribution by all.

• Tell Us Once&ndash;Final Phase goes live

  - by BizTalk Visionary

  Yesterday the final phase of ‘Tell Us Once’ went live. This completes the 4 1/2 year journey Solidsoft started on this cross government project with the addition of full electronic distribution of data and the most import piece – access for the citizen to use the service on-line. Tell Us Once (TUO) is the award-winning, cross-government programme that lets people inform central government and local authorities just once of a birth or death. In service in over 95% of councils in England, Scotland and Wales, it provides a permanent solution to the long-standing and frustrating issue of people having to notify the government multiple times. Several years ago, research showed that people had to make up to 44 contacts when reporting a death to government bodies and their local authority. The TUO service is offered as a face-to-face interview by the local authority or by telephone to a dedicated telephony service run by the Department for Work and Pensions (DWP). and a  now a TUO online service for death. From the bereavement section of the  Direct Gov web site the citizen is able to ‘enrich’ the standard death registration data to allow the ‘Tell Us Once’ system inform the various government departments about the death. These include the local council, DVLA, DWP, Passport service and HMRC. For the record this is an excellent example of how an SME working with a large SI partner can deliver success for government in a responsive and agile manner. For me personally it is a proud moment in which a vision I started with a very small team was followed through, extended and finally delivered by an excellent team at Solidsoft.

• Pros and Cons between learning to program on Windows and Linux and Macs

  - by Amumu

  I have been studying IT for 2 years and I'm going to graduate soon in this year (if everything goes well). I think it's time for me to choose a path to specialized into some fields of this large industry. Personally, I want to be a game programmer. But to be a game programmer, surely I have to invest my time to study Windows Programming, then DirectX and other programming techniques related to game. On the other hand, Linux seems promising as well. I am not sure about Game Programming on for it, but it seems become an expert for this OS, and by expert it's not about using the OS to become an administrator, but can do further than that, such as understand the OS to its essence and can produce applications for it. However, there's some obstacles in my view for this development path. Many of my friends think that Linux is based on free and open source, and if you follow it, as its name suggested: Free and Open Source, it means we also give away our software free. Otherwise, we will have to find a second job to make living. Currently, I think a viable way to make money on Linux is doing works related to client-server. Another way to developer my career is to become expert in developing business applications for companies. This is more on business, not on specialized IT fields so I am not really interested. Another alternative is programming on mobile devices, such as iPhone, Android and it seems very promising and easier to approach. Another way is to become a computer scientist and research on academic subjects such as AI, human-computer interaction, but this is far beyond my reach, so I won't invest my time on it until I feel I am experienced enough. That's all I can think of for now. I may miss a lot of things, so I need more opinions as input to get the big picture of the industry for my career path.

• Running CORN job on Ubuntu server for SugarCRM

  - by Logik

  i am pretty inexperienced in Linux.So be descriptive on your answer. My environment :Local Linux server 12.04 hosting Sugar CRM 6.5.2. There is area in sugar CRM called scheduler. I can configured some predefined jobs here. in my case i am trying to run email reminders (ever min/hour/day/month). For this scheduler to be effective, i read some where i need to setup CRON job. So i did some research & finally put following lines in CRONTAB for the root user, as per instructions given in sugarCRM. cd /var/www/crm; php -f cron.php /dev/null 2&1 Well i am creating contracts in my sugarCRM (AOS module) & i want email reminders to be sent for these contracts to the concern person. Now my sugarCRM email is configured correctly & i can send test emails using it. But the CRON + scheduler not giving any result. I can't receive any emails. Then i tried to read /var/log/syslog & it is showing entry for following line each minute. Oct 27 15:03:01 unicomm CRON[28182]: (root) CMD (cd /var/www/crm; php -f cron.php /dev/null 2&1) I've few questions: 1) what does the CRON job line i've added in crontab mean? cd /var/www/crm; php -f cron.php /dev/null 2&1 is not making any sense to me. 2) How am i suppose to get this thing work? I've searched a lot (including SugarCRM forum), but no luck.

• Field symbol and Data reference in SAP-ABAP

  - by PDP-21

  If we compare field symbol and data refernece with that of the pointer in C i concluded that :- In C language, Say we declare a variable "var" type "Integer" with default value "5". The variable "var" will be stored some where in the memory and say the memory address which holds this variable is "1000". Now we define a pointer "ptr" and this pointer is assigned to our variable. So, "&ptr" will be "1000" and " *ptr " will be 5. Lets comapre the above situation in SAP ABAP. Here we declare a Field symbol "FS" and assign that to the variable "var". Now my question is what "FS" holds ? I have searched this rigorously in the internet but found out many ABAP consultants have the opinion that FS holds the address of the variable i.e. 1000. But that is wrong. While debugging i found out that fs holds only 5. So fs (in ABAP) is equivalent to *ptr (in C). Please correct me if my understanding is wrong. Now lets declare a data reference "dref" and another filed symbol "fsym" and after creating the data reference we assign the same to field symbol . Now we can do operations on this field symbol. So the difference between data refernec and field symbol is :- in case of field symbol first we will declare a variable and assign it to a field symbol. in case of data reference first we craete a data reference and then assign that to field symbol. Then what is the use of data reference? The same functionality we can achive through field symbol also.

• Software Center empty "No usefulness from server" "no username in config file"

  - by Theron G. Burrough

  I upgraded to 12.04 LTS and ran Software Center while a few things were running, and crashed. (2 GB RAM on a Netbook.) On reboot, Ubuntu One interface would not find any programs, neither installed (to run) nor available for download. So I launched Software Center, which opens, but does nothing. I click "Close" button and get a "Force Quit?" box. So I quit. Did research, learned to run Software Center from Terminal: 2012-04-29 23:14:36,978 - softwarecenter.backend.reviews - WARNING - Could not get usefulness from server, no username in config file Then tried the below without success: Reinstallation of software center: sudo apt-get install --reinstall software-center Didn't work. Found this in a post: remove the config file for software-center then log out and back in sudo rm -rf ~/.config/software-center Didn't work. Reinstalled Software Center with Synaptic Package Manager. Still no dice! And I am a Linux newbie, so I don't know where the Dickens that config file is. Help appreciated.

• Scaling along an arbitrary axis (Dealing with non-uniform scale)

  - by Jon

  I'm trying to build my own little engine to get more familiar with the concepts of 3D programming. I have a transform class that on each frame it creates a Scaling Matrix (S), a Rotation Matrix from a Quaternion (R) and concatenates them together (S*R). Once i have SR, I insert the translation values into the bottom of the three columns. So i end up with a transformation matrix that looks like: [SR SR SR 0] [SR SR SR 0] [SR SR SR 0] [tx ty tz 1] This works perfectly in all cases except when rotating an object that has a non-uniform scale. For example a unit cube with ScaleX = 4, ScaleY = 2, ScaleZ = 1 will give me a rectangular box that is 4 times as wide as the depth and twice as high as the depth. If i then translate this around, the box stays the same and looks normal. The problem happens whenever I try to rotate this scaled box. The shape itself becomes distorted and it appears as though the Scale factors are affecting the object on the World X,Y,Z axis rather than the local X,Y,Z axis of the object. I've done some pretty extensive research through a variety of textbooks (Eberly, Moller/Hoffman, Phar etc) and there isn't a ton there to go off of. Online, most of the answers say to avoid non-uniform scaling which I understand the desire to avoid it, but I'd still like to figure out how to support it. The only thing I can think off is that when constructing a Scale Matrix: [sx 0 0 0] [0 sy 0 0] [0 0 sz 0] [0 0 0 1] This is scaling along the World Axis instead of the object's local Direction, Up and Right vectors or it's local Z, Y, X axis. Does anyone have any tips or ideas on how to handle construction a transformation matrix that allows for non-uniform scaling and rotation? Thanks!

• Last Chance At Space

  - by Grant Fritchey

  All entries for the DBA In Space contest have to be in by this Friday, the 18th. I’m so jealous of all of you who can enter this contest. Just think about it. You’re getting a chance to take a sub-orbital rocket ride. But, here’s the kicker, the chances are limited to data professionals. That’s a pretty small sub-set when you think about it. Further, you have to gotten the answers to the quiz questions correct, which only takes a little bit of honest research, but come on. That further limits the result set. You’ve really got an excellent shot at this (and the jealousy rears it’s ugly head again). If you haven’t finished your entry, go on over to the link and get it taken care of. There’s really no reason to not do it. Oh, and by the way, if you’re one of those (I’d say crazy) people who don’t want to ride the rocket, you can take the prize in cash. Although I’d be mighty disappointed in you if you did.

• Windows Azure Horror Story: The Phantom App that Ate my Data

  - by jasont

  Originally posted on: http://geekswithblogs.net/jasont/archive/2013/10/31/windows-azure-horror-story-the-phantom-app-that-ate-my.aspxI’ve posted in the past about how my company, Stackify, makes some great tools that enhance the Windows Azure experience. By just using the Azure Management Portal, you don’t get a lot of insight into what is happening inside your instances, which are just Windows VMs. This morning, I noticed something quite scary, and fittingly enough, it’s Halloween. I deleted a deployment after doing a new deployment and VIP swap. But, after a few minutes, the instance still appeared in my Stackify dashboard. I thought this odd, as we monitor these operations and remove devices that have been deleted. Digging in showed that it wasn’t a problem with Stackify. This instance was still there, and still sending data. You’ll notice though that the “Status” check shows that the instance no longer exists. And it gets scarier. I quickly checked the running services, and sure enough, the Windows Azure Guest Agent (which runs worker roles) was still running: “Surely, this can’t be” I’m thinking at this point. Knowing that this worker role is in our QA environment, it has debug logging turned on. And, using our log file tailing feature, I can see that, yes, indeed, this deleted deployment is still executing code. Pulling messages off queues. Sending alerts. Changing data. Fortunately, our tools give me the ability to manually disable the Windows service that runs this code. In the meantime, I have contacted everyone I know (and support) at Microsoft to address this issue. Needless to say, this is concerning. When you delete a deployment, it needs to actually delete. Not continue to eat your data. As soon as I learn more, I’ll be posting an update.

• Generic software code style enforcer

  - by FuzziBear

  It seems to me to be a fairly common thing to do, where you have some code that you'd like to automatically run through a code style tool to catch when people break your coding style guide(s). Particularly if you're working on code that has multiple languages (which is becoming more common with web-language-x and javascript), you generally want to apply similar code style guides to both and have them enforced. I've done a bit of research, but I've only been able to find tools to enforce code style guidelines (not necessarily applying the code style, just telling you when you break code style guidelines) for a particular language. It would seem to me a reasonably trivial thing to do by just using current IDE rules for syntax highlighting (so that you don't check style guide rules inside quotes or strings, etc) and a whole lot of regexes to enforce some really generic things. Examples: if ( rather than if( checking lines with only whitespace Are there any tools that do this kind of really generic style checking? I'd prefer it to be easily configurable for different languages (because like it or not, some things would just not work cross language) and to add new "rules" to check new things.

• Parsing mathematical experssions with two values that have parenthesis and minus signs

  - by user45921

  I'm trying to parse equations like these which only has two values or the square root of a certain value from a text file: 100+100 -100-100 -(100)+(-100) sqrt(100) by the minues signs, parenthesis and the operator symbol in the middle and the square root, and I have no idea how to start off... I've got the file part done and the simple calculation parts except that I couldnt get my program to solve the equations in the above. #include <stdio.h> #include <string.h> #include <stdlib.h> #include <math.h> main(){ FILE *fp; char buff[255], sym,sym2,del1,del2,del3,del4; double num1, num2; int ret; fp = fopen("input.txt","r"); while(fgets(buff,sizeof(buff),fp)!=NULL){ char *tok = buff; sscanf(tok,"%lf%c%lf",&num1,&sym,&num2); switch(sym){ case '+': printf("%lf\n", num1+num2); break; case '-': printf("%lf\n", num1-num2); break; case '*': printf("%lf\n", num1*num2); break; case '/': printf("%lf\n", num1/num2); break; default: printf("The input value is not correct\n"); break; } } fclose(fp); } that is what have I written for the other basic operations without parenthesis and the minus sign for the second value and it works great for the simple ones. I'm using a switch method to calculate the add, sub, mul and divide but I'm not sure how to properly use the sscanf function (if I am not using it properly) or if there is another way using a function like strtok to properly parse the parenthesis and the minus signs. Any kind help?

• Writing Acceptance test cases

  - by HH_

  We are integrating a testing process in our SCRUM process. My new role is to write acceptance tests of our web applications in order to automate them later. I have read a lot about how tests cases should be written, but none gave me practical advices to write test cases for complex web applications, and instead they threw conflicting principles that I found hard to apply: Test cases should be short: Take the example of a CMS. Short test cases are easy to maintain and to identify the inputs and outputs. But what if I want to test a long series of operations (eg. adding a document, sending a notification to another user, the other user replies, the document changes state, the user gets a notice). It rather seems to me that test cases should represent complete scenarios. But I can see how this will produce overtly complex test documents. Tests should identify inputs and outputs:: What if I have a long form with many interacting fields, with different behaviors. Do I write one test for everything, or one for each? Test cases should be independent: But how can I apply that if testing the upload operation requires that the connect operation is successful? And how does it apply to writing test cases? Should I write a test for each operation, but each test declares its dependencies, or should I rewrite the whole scenario for each test? Test cases should be lightly-documented: This principles is specific to Agile projects. So do you have any advice on how to implement this principle? Although I thought that writing acceptance test cases was going to be simple, I found myself overwhelmed by every decision I had to make (FYI: I am a developer and not a professional tester). So my main question is: What steps or advices do you have in order to write maintainable acceptance test cases for complex applications. Thank you.

• My new favourite traceflag

  - by Dave Ballantyne

  As we are all aware, there are a number of traceflags.  Some documented, some semi-documented and some completely undocumented.  Here is one that is undocumented that Paul White(b|t) mentioned almost as an aside in one of his excellent blog posts. Much has been written about residual predicates and how a predicate can be pushed into a seek/scan operation.  This is a good thing to happen,  it does save a lot of processing from having to be done.  For the uninitiated though: If we have a simple SELECT statement such as : the process that SQL Server goes through to resolve this is : The index IX_Person_LastName_FirstName_MiddleName is navigated to find the first “Smith” For each “Smith” the middle name is checked for being a null. Two operations!, and the execution plan doesnt fully represent all the work that is being undertaken. As you can see there is only a single seek operation, the work undertaken to resolve the condition “MiddleName is not null” has been pushed into it.  This can be seen in the properties. “Seek predicate” is how the index has been navigated, and “Predicate” is the condition run over every row,  a scan inside a seek!. So the question is:  How many rows have been resolved by the seek and how many by the scan ?  How many rows did the filter remove ? Wouldn’t it be nice if this operation could be split ?  That exactly what traceflag 9130 does. Executing the query: That changes the plan rather dramatically, and should be changing how we think about the index seek itself.  The Filter operator has been added and, unsurprisingly, the condition in this is “MiddleName is not null” So it is now evident that the seek operation found 103 Smiths and 60 of those Smiths had a non-null MiddleName. This traceflag has no place on a production system,  dont even think about it

• The remote server returned an error: 227 Entering Passive Mode

  - by hmloo

  Today while uploading file to FTP sever, the codes throw an error - "The remote server returned an error: 227 Entering Passive Mode", after research, I got some knowledge in FTP working principle. FTP may run in active or passive mode, which determines how the data connection is established. Active mode: command connection: client >1024  -> server 21 data connection:    client >1024  <-  server 20 passive mode: command connection: client > 1024 -> server 21 data connection:    client > 1024 <- server > 1024 In active mode, the client connects from a random unprivileged port (N > 1023) to the FTP server's command port(default port 21). If the client needs to transfer data, the client will use PORT command to tell the server:"hi, I opened port XXXX, please connect to me." and then server will use port 20 to initiate the data connection to that client port number. In passive mode, the client connects from a random unprivileged port (N > 1023) to the FTP server's command port(default port 21). If the client needs to transfer data, the sever will tell the client:"hi, I opened port XXXX , please connect to me." and then client will initiate the data connection to that sever port number. In a nutshell, active mode is used to have the server connect to the client, and passive mode is used to have the client connect to the server. So if your FTP server is configured to work in active mode only or the firewalls between your client and the server are blocking the data port range, then you will get error message, to fix this issue, just set System.Net.FtpWebRequest property UsePassive = false. Hope this helps! Thanks for reading!

• XNA 4.0, Combining model draw calls

  - by MayContainNuts

  I have the following problem: The levels in my game are made up of a Large Quantity of small Models and because of that I am experiencing frame rate problems. I already did some research and came to the conclusion that the amount of draw calls I am making must be the root of my problems. I've looked around for a while now and couldn't quite find a satisfying solution. I can't cull any of those models, in a worst case scenario there could be 1000 of them visible at the same time. I also looked at Hardware geometry Instancing, but I don't think that's quite what I'm looking for, because the level consists of a lot of different parts. So, what I'd like to do is combining 100 or 200 of these Models into a single large one and draw it as a whole 'chunk'. The whole geometry is static so it wouldn't have to be changed after combining, but different parts of it would have to use different textures (I think I can accomplish that with a texture atlas). But I have no idea how to to that, so does anybody have any suggestions?

• Subdomain still times out after set up a month ago

  - by user8137

  I'm a newbie on this and this has probably been asked already but the subjects online were close but too vague in there answers so I've probably really messed this up. I would really appreciate specific step by step instructions. This is what I'd like to do: use the subdomain www.high-res.domain.com to be accessed by external customers with specific permissions to access the site (like ftp). We use Network Solutions to house domain.com. We recently added a new ip address to point to www.high-res.domain.com. I gave the ip address to the company that hosts our website. I pinged www.high-res.domain.com and it points to the correct ip address but still times out. It’s been a few weeks now and when you ping it, it still times out. C:ping XXX.XXX.X.XXX Pinging XXX.XXX.X.XXX with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for XXX.XXX.X.XXX: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss). Tracert times out as well. I even went to DNS tools and a few other sites for checking this and it shows the same thing. I recently went into the DNSmgmt on our server (wink2k3sp1) and created an A record under the DomainDnsZones which translated to a Cname when you look at it. Under the Domain it has two entries one to the subdomain and the other to the website host each with separate ip addresses. Is this correct? The website people are too busy on another project to research it further and my friends haven't gotten back to me. Please help. Thanks KK

• How to install Tor (Web Browser) in Ubuntu 12.10?

  - by Zignd

  I would like to install the Tor, but I'm having some problems. I know that someone will say "This question is a exactly duplication of How to install tor?", but it's not, because the another question can not be applied to Ubuntu 12.10 as the deb command is not available anymore. I did a research and even at the Tor's Official Website the available resource can not be applied to Ubuntu 12.10. I tried to use the deb command (as the above question says: deb http://deb.torproject.org/torproject.org <DISTRIBUTION> main) and the Terminal says deb: command not found and when I try to install it says E: Unable to locate package deb. I've also tried to use the ppa: ubun-tor, but it's not compatible with Quantal Quetzal, because it's too old. I've also tried to use sudo apt-get install tor, but browser icon don't shows up after installation and if you try to use the command tor in the Terminal I get the following error message: Nov 26 10:59:25.731 [notice] Tor v0.2.3.22-rc (git-4a0c70a817797420) running on Linux.

• How to REALLY start thinking in terms of objects?

  - by Mr Grieves

  I work with a team of developers who all have several years of experience with languages such as C# and Java. Most of them are young enough to have been shown OOP as a standard way to develop software in university and are very comfortable with concepts such as inheritance, abstraction, encapsulation and polymorphism. Yet, many of them, and I have to include myself, still tend to create classes which are meant to be used in a very functional fashion. The resulting software is often several smaller classes which correctly represent business objects which get passed through larger classes which only supply ways to modify and use those objects (functions). Large complex difficult-to-maintain classes named Manager are usually the result of such behaviour. I can see two theoretical reasons why people might write this type of code: It's easy to start thinking of everything in terms of the database Deep down, for me, a computer handling a web request feels more like a functional operation than an object oriented operation when you think about Request Handlers, Threads, Processes, CPU Cores and CPU operations... I want source code which is easy to read and easy to modify. I have seen excellent examples of OO code which meet these objectives. How can I start writing code like this? How I can I really start thinking in an object oriented fashion? How can I share such a mentality with my colleagues?

• Extremely simple online multiplayer game

  - by Postscripter

  I am considering creating a simple multiplayer game, which focuses on physics and can accommodate up to 30 players per session. Very simple graphics, but smart physics (pushing, weight and gravity, balance) is required. After some research I found a good java script (framework ??) called box2d.js I found the demo to be excellent. this is is kind of physics am looking for in my game. Now, what other frameworks will I need? Node.js?? Prototype.js?? (btw, I found the latest versoin of protoype.js to be released in 2010...?? is this still supported? Should I avoid using it?) What bout HTML 5 and Canvas? would I need them? websockets? Am a beginner in web programming + game programming world. but I will learn fast, am computer science graduate. (but no much web expeience but know essentionals javascript, html, css..). I just need a guiding path to build my game. Thanks

• What is the best approach to solve a factory method problem which has to be an instance?

  - by Iago

  I have to add new funcionality in a web service legacy project and I'm thinking what is the best approach for a concrete situation. The web service is simple: It receives a XML file, unmarshalling, generates response's objects, marshalling and finally it sends the response as a XML file. For every XML files received, the web service always responds with the same XML structure. What I have to do is to generate a different XML file according to the XML received. So I have a controller class which has all marshalling/unmarshalling operations, but this controller class has to be an instance. Depending on XML received I need some marshalling methods or others. Trying to make few changes on legacy source, what is the best approach? My first approach was to do a factory method pattern with the controller class, but this class has to be an instance. I want to keep, as far as it goes, this structure: classController.doMarshalling(); I think this one is a bit smelly: if(XMLReceived.isTypeOne()) classController.doMarshallingOne(); else if(XMLReceived.isTypeTwo()) classController.doMarshallingTwo(); else if(XMLReceived.isTypeThree()) classController.doMarshallingThree(); else if ... I hope my question is well understood

• Cleaning Up After Chrome

  - by Mark Treadwell

  I find Google Chrome, which I have no interest in, is continually getting installed on machines in my house, mostly due to Adobe Shockwave bringing it along as an install package. (Family members are agreeing to the download, not realizing the Chrome is getting dropped as well.) My major issue after uninstalling Chrome is that you can no longer click on links in Outlook emails. There is a lot on the web about this, and Google has not been proactive at fixing their uninstaller. I have now added a registry file to my Win64 systems to reset the problem registry keys and clear the error. This registry file is pretty simple. It merely resets HKEY_CURRENT_USER\Software\Classes\.htm, HKEY_CURRENT_USER\Software\Classes\.html, and HKEY_CURRENT_USER\Software\Classes\.shtml back to their default values of "htmlfile". Chrome takes over the handling of these file extensions because its default install is to make itself the default web browser. The Chrome uninstalled fails to clear/reset them. In troubleshooting this, I looked in my registry based on the web info on the Chrome uninstall problem. Since my system had never had Chrome installed, my registry did not have the problem keys. To troubleshoot, I installed (ugh!) and uninstalled Chrome. Sure enough, Chrome left the expected debris with a value string of "ChromeHTML.PR2EPLWMBQZK3BY7Z2BFBMFERU" or something similar. Resetting these values fixed the problem. I see that Chrome leaves quite a bit of debris behind in the registry. I guess it is creating the keys then leaving them behind, even though their presence (with bad data) subsequently affects operations.

• How can I use the dualforward parameter in my unity shader to use lightmaps and normal maps together?

  - by Raphaeltm

  I'm using the free version of unity and I would like to combine lightmaps with specularity and normal maps. After doing a -bunch- of research, I've figured out that there doesn't seem to be any easy way to do this in the free version of unity, which doesn't support deferred rendering/easy use of dual lightmaps. However, it looks like it's possible, by writing a custom shader, using the "dualforward" parameter in a shader, switching the lightmapping mode to "dual lightmaps" and turning on "Use in forward ren." (basically, writing a shader that specifies the use of dual lightmaps, which should allow for a combination of lightmaps and normal maps) So I downloaded the source code for the default shaders (because all I need is a normal specular bumped shader) and added "dualforward" to the parameters: Shader "Bumped Specular Dual Lightmaps" { Properties { _Color ("Main Color", Color) = (1,1,1,1) _SpecColor ("Specular Color", Color) = (0.5, 0.5, 0.5, 1) _Shininess ("Shininess", Range (0.03, 1)) = 0.078125 _MainTex ("Base (RGB) Gloss (A)", 2D) = "white" {} _BumpMap ("Normalmap", 2D) = "bump" {} } SubShader { Tags { "RenderType"="Opaque" } LOD 400 CGPROGRAM #pragma surface surf BlinnPhong dualforward sampler2D _MainTex; sampler2D _BumpMap; fixed4 _Color; half _Shininess; struct Input { float2 uv_MainTex; float2 uv_BumpMap; }; void surf (Input IN, inout SurfaceOutput o) { fixed4 tex = tex2D(_MainTex, IN.uv_MainTex); o.Albedo = tex.rgb * _Color.rgb; o.Gloss = tex.a; o.Alpha = tex.a * _Color.a; o.Specular = _Shininess; o.Normal = UnpackNormal(tex2D(_BumpMap, IN.uv_BumpMap)); } ENDCG } FallBack "Specular" } This, however, doesn't seem to work. When I keep the "dualforward" param, every object that uses it seems to be lit by the one directional light in the scene. When I remove the "dualforward" param, it they look like normal lightmapped objects with no normal maps or specularity. I noticed that the support for "dualforward" seems to be new in v.3.4.2, so I made sure to download it (I was running 3.4.1), but it still doesn't work. Anybody have any advice for me?
