I'm using the Molecular Script add-on to create particles to fill a container. It's working well provided the particles aren't rotating. As soon as I add rotation, those that collide with the surface rotate as expected (with friction with the surface) and those that bounce off of each other also seem to rotate as expected, but those that become 'at rest' in the centre of the mass of particles continue to rotate - I would have expected friction with the neighboring particles to cause them to stop rotating.
I end up with something like the following :
I've tried all the particle settings (including Damping, Drag, Molecular Linking, etc.) but nothing appears to enable friction between these 'at rest' particles. How can I get my particles to stop when at rest?
Here's the full particle properties panel (apologies for the very tall image!) :
I've tried disabling the Dynamic option as suggested by Mateus but this stops all rotation - including rotation when rolling on the collision surface.
I'm wondering whether Molecular Script does not handle rotation at all - since on closer inspection the particle to particle collisions don't actually seem to be producing rotation either - and what I was seeing was the rotation from surface collision interactions only.
