basic RBD Glue object question

[hbiz]

I'm beginning my exploration of dops and I wanted to take a simple poly sphere, partition it into groups where each face is in its own group, then feed that into an rigid body sim to have it shatter against a static ground plane. Attached is a simple scene with my attempt to do this. The only issue is that some faces of the sphere remain unaffected and others pass through the floor. I'm not sure if I'm partitioning incorrectly or if my collision setup is incorrect.

Thanks for your time

Some of the pieces have zero volume (and hence zero mass), and the Bullet solver treats objects with a mass of zero as static objects. You can work around this by turning off the Compute Mass parameter and specifying your own mass.

thanks! that fixed it
