Is it possible to upload pre-rigged cahracters from CC3?

Hi Ussnorway, thank you for the help.  Maybe I will try to remove some chest bones, or extra bones exported in the FBX.  I am hoping that we can still create characters, like we did in Fuse but now with CC3, and import them into Mixamo.  Keeping the blend shapes would be essential.  I am hoping that Mixamo/Adobe realizes that people will want to use the CC3 character creation workflow, what with Fuse being EOL'd.  For my work, I use CAT in 3ds Max, so I would go Fuse -> Mizamo -> Max 2017 -> CATcript - > Max 2021.  That would give me custom characters, with blend shapes, in a CATrig, in the current Max.  Now I am wondering if I will ever be able to recreate that, again, sadly.
