One solution is to use clipbrush. It works great.
I want to add clipbrush to entity, but compilers stops with "Entity with no valid brushes or textures on line...".
How to assign cliprush to entity?
Thank you very much for reply
(Maybe Quake allows it but compilers deny it? Maybe I can program it? But it will take lot of time which I dont have. Maybe it can be suppressed in bsp compiler?)
