I’ve made some grass and I want to make texture shells for the game engine.
I made planes to separate what I want rendered. The problem is that I only want the grass rendered to a certain height (I only want the parts between the planes, a start and end).
Is there anyway I can do this? Or is it possible to “cut” particals?
I might have misunderstood your question,
but maybe the zmask feature is what you are looking for.
using cubes instead of planes and setting up zmask in the renderlayers would give you the posibility to “Cutout” your render in a certain space. http://www.blender.org/development/release-logs/blender-246/rendering-features/
