Hi,

I'm just starting with dynamica and maya. I shattered my geometry with houdini and imported it as obj. Then I created rbd's with a 0.0 geometry offset. Then I added some impulse rotation to the rigid bodies. Works fine so far. The speed of the simulation is a bit slow, I think it's because of the scaling. I think one maya unit is one meter in bullet? Okay downscaling makes the simulation faster. But in both cases I get jittering objects as soon as the objects should be resting. As an alternative I tried to increase gravity what works but gives me jittering objects as well.

Here are the tries:

http://www.haggi.de/zeuch/smallScale.mov
http://www.haggi.de/zeuch/smallScaleHighRot.mov
http://www.haggi.de/zeuch/smallScaleHighGrav.mov

Any ideas how to get rid of the jittering? Is the only way to try to increase the damping until the objects stops to move?

are those meshes or hulls? i have seen this when using the hull rigid body option on concave shapes. try using the mesh option when converting the pieces to rigid bodies.

It's all meshes, no hulls.
