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 ! 

BTW this is , as you can see, a standard character with no clothes. No duplicate texture names. But the log says that there is an 'unknown texture type' which is weird. 

When I try just adding one single texture, like the diffuse jpg for just the head, I get no errors but it still only gives me a texture layer for the left cornea. 

Use the Layer Palette and select Skin Head

In the Layer palette, there is no skin head layer. That's the problem. See the video that I posted above. There is only one layer, and that's for the cornea. The multiple layers are not being loaded into Substance Painter. 

this is what my layer palette looks like 

Sorry I mean texture set list
