Hi, guys!
I made a jacket in Maya 2018 for my CC character and followed this tutorial https://www.youtube.com/watch?v=BFWnWDUk2lM to bind jacket, copy skin weights, and export all that staff with jacket and body template to CC3.
In CC I went to Create - Cloths (with fbxkey file), added model and fbxkey file and got an error. The only information I found was a suggestion about fbx export from Maya. Like only fbx 2012 will be ok. Since I use Maya 2018 I didn't check that.
I tried to export with and without textures just in case, but it still didn't work.
