I've just started working with CC3 and am trying to figure out the CC-->UE4 workflow, and I've mostly got it except my foot weights come in wrong--it looks like a lot of the foot skin is actually bound to one bone up the hierarchy from where it should be (i.e. main foot bound to shin, toe bound to foot). I've tried recreating the boots in CC, calculating collisions, and re-transferring skin weights using the shoes template, but the result is the same (attached). What am I doing wrong?

I'm on a Mac, so the direct-import plugin is a nonstarter in this case.

Thanks for any help!

 I'm trying to figure out my own shoe problem in Unreal as well and came across this. Maybe it will help you.

Thanks--unfortunately that doesn't change anything on my guy.

Addendum to my last reply (currently awaiting approval)--while this fix did not work, using the high heels slider in CC3 and choosing the UE Mannequin skeleton on import did seem to do the trick!
