I'm currently trying to implement a type of "smooth" lighting. How can I achieve lighting which looks like this:

http://dl.dropbox.com/u/1668516/concept/warp3.png

Using OpenGl. I've attempted to use blending modes and have come very close to making it work but it came out like this: https://pbs.twimg.com/media/A1071viCEAAlFmJ.png

and I also wasn't able to change the alpha of the black background which I want to be able to do.

Could I get a few pointers in the right direction?

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
