I think that grass shader is only working on terrain right? Could it be re written to work on leveltextures? And would it be possible to use Models (spike pits, (I have a texture called spikes. If a entity steps on the texture it looses. Putting entities into alle these pits of different size would be a big waste. I think a shader would do that better. Important would be the same distant of every spike). I hope the entity is faded out if its to far away from the cam (like detail maps, which are only rendered of they are close to the cam. The distance should be adjustable).
