Hi,

I started learning DOP's recently. I have a doubt about collisions. I created a simple "rbdGluedObject" and made it fall from a certain height on to a ground plane, using gravity & rbdSolver . When the object touches the ground, it breaks into pieces, which is what i want. But the problem is, it is inter-penetrating the ground plane. In the collisions tab of the rbdObject, i chose the surface penetration type as "edges". Also after the object falls down on the ground, it keeps vibrating like crazy as well as penetrating the ground. Can someone tell me why this is happening ?

Thanks,
Sanjay

PS : I was practicing all these stuff at work, where we use houdini 10. I see this problem happening only with houdini 10. I did the same thing with houdini 9.5 apprentice version from home. It works perfectly.

Can you post the scene file?

Collision detection in Houdini is a bit shite, by ground plane you need to be using something with volume, the Ground Plane dop works, since it's just a grid extruded down.

Only right way to work with dops is using SDF stuff, there's already too much hassle already with it to try non-SDF stuff.
