Atom Posted May 22, 2017 Share Posted May 22, 2017 Your hip file is missing the external rock debris object that it references. Anytime you just copy geometry to points after a simulation there will be no enforced collision. You must send the pieces into the simulation so the simulator can collide correctly.

Atom Posted May 22, 2017 Share Posted May 22, 2017 There are some examples on this forum. Basically search on packed primitives. Here is a link to one such setup. https://www.sidefx.com/forum/topic/49477/#post-223555 You can also click on the link in my signature and find a few more. 1 Quote Link to comment Share on other sites More sharing options...
