Collisions works better now. I tested it in more scenarios: meshes with negative scale, meshes with holes, wrong normals, shape keys animated, and etc.
Now I'm testing wind simulation scenarios, more than one rig scenarios and all of that in most extreme way possible.
Cause again: I'm a heavy overthinker xd
-Wiggle physics enabled
-There is a crazy wind in the scene that constantly changes its value
-Tomas's head is animated
-4 collision objects of different shapes, and all of this works in real-time.
The hybrid XPBD solver works much more stably than the old one, I already really want to release the add-on, but I want to make sure it is ready for production cause you know, I'm a heavy overthinker lol
