I’m trying to mimic a form Anish Kapoor would maybe create by having a loosely inflated ball draped over a wall. I don’t want the mesh of the ball to collapse over itself, so I would like to introduce self-collision…this is where I’m having trouble.

I’m attempting to use the standard technique where you apply the collision spheres to each vertices of the mesh (using the default radius of 1). But when I attempt to run this, the inflated sphere vanishes immediately. Any idea where I could be going wrong?

As a side note…I’m having trouble determining when I should use Kangaroo’s ‘mesh edges’ component vs. the ‘length’ component when dealing with mesh deformations. Any clarity would also be appreciated.
