Here's the situation. I want several brush entities with displacement maps to appear and disappear. So, I decide I'll go with a func_brush, because IIRC those can be made to disappear and reappear whenever. But I make my brushes into func_brushes and I get this error when I compile:

Error: displacement found on a(n) func_brush entity - not supported

Uh, anyone have any ideas for a workaround? I suppose I could make teleporting train entities and all, but that would be such a pain, ugh.

Yeah I remember that, it was in that huge 600mb movie thing. The dude said the terrain was able to move in game :/ I don't see any of that! Maybe there just wasn't any point for it in the game... Would've been cool though

I definitely read something about *deformable terrain* existing in the game, somewhere before buying it. Don't remember exactly where though. Hell it might have even been on the box. I don't recall seeing any actual terrain deformation throughout the entirity of the SP game. Holes appearing in cement floors for ants to come through certainly don't count since I assume they simply moved (or removed) the block entities that were covering them.
