Hi. I've tried exporting a number of CC3 characters (from V3.21), made with official clothing into Unity 2018.2.18. When animated, the result is fairly severe distortion, typically around the shoulders and chest. I have attached an image to demonstrate. Can anyone offer guidance on how to make these models usable? Thanks!

A quick follow up. This was caused by the number of bones on the skinned mesh renderer being set to 1. Increasing to 2 or 4 bones resolves the issue.
