TrueGrit by Andrew Reid – TrueGrit is a free dirt simulation plugin. As of version 0.2b, TrueGrit can use an object’s vertex color channel to store grit information instead of using a bitmap. This way users don’t need to set up mapping coordinates for their objects in order for the grit generation to work (it does require added mesh density, though).
Plugin Update – TrueGrit v0.24b
