Hi! I can't find any system for detecting and preventing self-trapping. I.e when cloth folds in on itself and gets stuck in its own self-collision. Do you have any suggestion as to how to prevent this?

Hi,

There's no way to prevent this in the general case, as it is a form of tunneling. Increasing the amount of solver substeps/ decreasing the tilmestep might help.

Thanks for the fast reply.
I'll try that, and then eventually dive down in to the API and see what I can do there.
