I'm at the point where I want to tweak my map lighting, and I've no experience with using the env_projectedtexture. Reading the Valve wiki has helped somewhat, but WHAT TEXTURE should I be setting for the light? I can't find any examples of common texture names that were used in valve maps. What are you guys using? Thanks.

For my maps I am using the standard texture.
I think the original Valve maps use it too.
Give it a try.

I've used effects/flashlight001 and effects/flashlight002 after checking some Valve maps. (Altough I'm note sure that changing them has any effect at all, I haven't experimented with them much..)

For finding the right texture, look at this: post47177.html#p47177

That's just what I was looking for. I had seen it before but couldn't find it. Thanks
