lighting

I am trying to figure out how line-shaped lights fit into the standard point light/spotlight/directional light scheme.

The way I see it, there are two options:

Seed the line with regular point lights and just deal with the artifacts. Easy, but seems wasteful.
Make the line some kind of emissive material and apply a bloom effect. Sounds like it could work, but I can't test it in my engine yet.

Is there a standard way to do this? Or for non-point lights in general?

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

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).
