I made a very simple scene with a Ground Plane and a bouncing Sphere by making the Sphere an RBD Object.

I notice that when the Sphere is a Primitive, it bounces in the Z direction.
NURBS, Bezier, Mesh, and Poly Mesh all bounce perfectly up and down.

I understand why a polygon sphere might bounce sorta erratically, but I don't understand why a sphere primitive wouldn't bounce perfectly.

I think I'm missing a basic understanding of what a primitive is and how/why it acts differently in a simulation.

Can someone please explain this to me?

BTW, I did increase the Bounce for the GroundPlane & Sphere using the Physical Tabs in their respective nodes in the AutoDopNetwork. But I don't think this is what's at issue.

I've noticed that Box Picking selects through an object (i.e. verticess on opposite side are selected).

Lasso & Brush do not do this.
Is this the expected behavior - is this a bug that should be reported - or is there a setting that i'm missing?


BTW, is the number of selected vertices, edges, primatives/polys displayed anwhere?

thanks, guys.

Here's another post that helps too…
