Creating one shader node in Maya from multiple texture sets...

Hi folks, got a question.

I see UDIM textures that combine to form one shader network in Maya. How is this done in Painter, exactly? Can it be done? So far, my research on this says that the only hope is a script that's supposed to combine them for you into one set. But, this has yet to work for me.

Multiple texture sets ultimately create multiple shader networks. Is there not a way to generate textures that combine the various sets so that you don't need 7 shader networks for one model?

Thanks!
