I recently read this GPU GEMS 3 article Volumetric Light Scattering as a Post-Process. I like the idea to add volumetric light property to realtime render i'm working on. Question is will it work for multiple lights? Our renderer uses one render pass per light and uses additive blending to sum incoming light.

I'm mostly convinced that it have to work nice. Do you agree? Maybe there can be problem where light rays crosses each other.

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
