i am working on a film for a school project and am looking for some help creating the grass that we need for our film and getting it to react dynamically with characters and wind. what we have so far is a polygonal landmass with maya fur grass attached to the surface. we have created character collision rigs from collide spheres and cubes and are going to implement those react to effect a hair system in which the collisions from the character rigs will drive the maya fur grass. So here are the main points.
For fairly large area maya fur works pretty well to create the grass we need however closeup shots of which there are only a few tend to not look as good as i would like them. I know grass can be created with paint fx and even just modeling it as well. Does anyone have a good recommendation of how to go about getting the grass to look good without adding an intense amount of render time.
We are having trouble getting the collision rigs to effect the hair system in the way we would like it to. We want the grass to move as the characters walk through it as well as bend to the ground when the characters walk over it. The film takes place in a swamp so this is a pretty big technical aspect that needs to be worked out. If anyone has any addition information or suggestions on ways to improve what we are looking for a would really appreciate the help.
