Issue with rolling balls (Physics)

[austinb31862280]

I was wondering if anyone might be able to tell me a good way to make a circle object or puppet roll. This seems like it should be simple. Just set the mesh shape to contour, and done.. but the issue is that it doesn't stay on the ground when rotating, when it gets to the corner of the selection or bounding box, it acts like it's a square object. I'm unsure of how to post GIFs or examples, so I can't show this happening at the moment. It's easy to replicate. Create a circle shape in Photoshop, and try to make it role against the ground. If you have any tips or luck with this, I would greatly appreciate it.

Thanks,

I think there was a “fast” setting for collisions somewhere. I wonder if that does bounding box as the estimate. I think I have seen balls roll, so I am pretty sure it is possible. There are friction settings too (not at computer sorry). I had a soccer ball bounce and roll.

Have you tried turning on mesh in CH? There is a button at bottom of scene And rig panes. Maybe there is something hidden?

Sorry, don’t have access to a computer for a few days.

Thank you for your help. I must have changed the friction settings by mistake. I also found a layer that was not agreeing with the overall contour of the ball. It rolls now. Not perfectly, but I think I know how to fix that.

Thanks
