Xgen UDIM maps for hair color

[RobinBlake]

Hi, Im currently trying make a groom for a mouse. I know xgen does not like UDIMs so I created a 'scalp' mesh where my UVs are in 0-1 but I would like drive the color of the fur with my base textures on the mesh with UDIMs but I cannot seem to find a way to achieve this?  

I was thinking perhaps a 2nd UVset on my scalp mesh to assign the shader to but have not had luck figuring out how to set it up or if it even can be. Any help would be greatly appreciated! been trying to google for hours.

In talking with a friend I think my solution will just be to transfer the textures in Mari from my UDIM model to the single UV set model to then drive the hair color. Just wish that xgen / maya painting tools was able to deal with UDIMS.
