The problem is that the chain is constantly breaking. Increasing substeps in the rigidbodysolver seems to help keep the chain alone intact, however as soon as I introduce the box, no amount of increasing substeps does the trick.
Can anyone please tell me where I'm going wrong?
I've taken a look at Rigid Body Solver Settings - Chain Simulation [www.sidefx.com] however my understanding of houdini is too basic to fully follow the suggested VDB to Spheres method and the reasoning behind it.
