Collision textures

It says its possible (command ref) but is it possible with a b3d format? That is grabing the collided entity's texture, and hopefully getting the file name?

You need to get the triangle collided, then the brush, then the texture.

I have seen it done somewhere...

But not on a lightmaped mesh right?

Mmm, not sure...sorry...

Can't you use the GetSurface() command, then GetBrush() then GetBrushTexture() command?
