I want a specific brush to not cast shadows and yet be visible and opaque in the game. Is there some way to set this in the shaders - so for instance a given texture is ignored during the LIGHT phase of the compiling?

Add an alpha channel to your texture and make it all transparent. Then add

Code: Select all

surfaceparm alphashadow

to your shader.
That should do the trick.

Hmm..

The shader for that texture looks like this:

textures/altars/lamp
{
surfaceparm alphashadow
}

Is that what you meant? What I get from this is the exact opposite of what I had in mind; the texture is invisible to the player but it casts a shadow.

I think I need to spend some time at the link you gave me..
