I haven't figured out how to add comments in this forum for already existing issues to track them, so I am repeating the issue...
Any fbx import from 3dxchange, Iclone, or CC3 to Maya 2020.1 will crash horribly. You've mentioned in another post you'll fix it. I've just bought CC3 pipeline and it's still there - I can't make my task I've bought for the CC3.
