Hello everyone. 
I have followed the instructions, documentation, video, etc. precisely about 10 times or so but I can't seem to get the UDIM workflow working for CC3 > Substance Painter. 

This video outlines what's happening:

In a nutshell, when I export from CC3, I then import and check all of the appropriate boxes, add all of the texture files, etc. and then for whatever reason, in Substance, only the STD_Cornea_L texture is loaded. I can paint my character's left eye, but nothing else. 

This forum has been great so far; any help on this would be appreciated , Thanks !
