lighting

Off the back of this post in which I asked two questions and received one answer, which I accepted as a valid answer. I have decided to re-ask the outstanding question.

I have implemented light points with shadow casting as shown here but I would like an overall map light with no point/light source.

The map setup is a top-down 2-d 50X50 pixel grid.

How would I go about implementing a day/night cycle lighting across a map?

My game uses the Content Pipeline to load the spriteSheet at runtime. The artist for the game sends me the modified spritesheet and I do a build in my machine and send him an updated project.

Is there any difference between storing textures and baked lighting for environment meshes?

as seen on Game Development - Search for 'Game Development'
I assume that when texturing environments, one or several textures will be used, and the UVs of the environment geometry will likely overlap on these textures, so that e.g. a tiling brick texture can be used by many parts of the environment, rather than UV unwrapping the entire thing, and having several… >>> More

Blender Object Appearing Gray when all Lights are Off

I have an issue with Blender where, when I turn my only light off (a sun lamp) and render the image my object appears gray rather than black (and thus, not appear to the camera). I can't figure out why this is happening. Here's what I just did in my scene: Added a new UV Sphere mesh (to make a… >>> More
