Cloth distortion

Hello all.

I have very embarassed problem. It happens to me many times. After i created mesh in Blender, lets say in my case long coat, i wanted add nice gently cloth physics movement. Its already skinned mesh, i setup all in cloth component and when i hit play button wow is so nice, no problem. Then i add surface penetration and when i hit play button again..wohoo.Something flying around! like broken mesh...Gif included. I tried clean mesh, reduced mesh polygons but everytime is this! Gah, please help me. Im still noobish in Unity.

Thank you very much

You should probably add some capsule / sphere-pair colliders to help the cloth not intersect itself. We found that using the self-intersection option in the Physics Setting and painting those weights caused things to become slow/unstable for large meshes... Hopefully the colliders help a bit?

 

Thank you for your answer. Yes, i using now sometimes colliders that helps.But i cleaned UV map and polygons and that helped too. Thank you
