Disappearing displacement map entites

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.

Ok, AND I tried a func_movelinear and it didn't work either! Sheeeesh.

Another method of making things disappear is making them func_doors and
setting their speed really high so you can't see them move.

From the SDK docs: Displacements are also static in the game -- they cannot be moved, animated, or attached to any entity in the engine.

Gotcha, thanks...I'm just going to have to do something else then.

What about the demo they showed ages ago with the moving piece of terrain (it was as if there was an earthquake or something - the terrain moved unevenly)? I'm also sure I noticed an entity with a name that suggested it modified a displacement surface. I'm not at home just now, but I'll check when I get back.

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 :sad:

I believe env_terrainmorph would do exactly this, but it's used for distorting the displacement surface, not actually moving the displaced object.

BTW...consider this question answered...

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.
