The simplicity of the odforce example [odforce.net] on rigid body dynamics made me think I could adapt it to a project of mine without trouble. Not so! I want my particles to interact with each other as tiny spheres, but I've only been able to achieve this when each particle is instanced by a unique piece of geometry, which would be impractical for thousands of particles. The RBD Create POP advertizes “It modifies input particles to make them into rigid body particles,” but why is it that when I pipe several particles into it, check the “Make Input Particles Rigid Bodies” flag, and give it my sample sphere either as Particle Geometry or in an Instance POP up the pipe, I only get one sphere translated the same as on the geometry level?
I'm probably just not doing it right, but perhaps this is a practical limitation of RBD; maybe it was never meant to handle hordes of particles. In which case, another question: How would I simulate surface and internal friction with the Interact POP? Like the Collision POP, except between particles?
thanks in advance, you guys have been a real help so far!
