Nexttut covers the processes for creating UDIMs in Maya and Substance 3D Painter.
With the low/high model workflow, you can create single or multiple-tile UVs. If you are making the latter, look at this tutorial from the folks at NextTut.
The tutorial shows how to create UDIM tiles in Autodesk Maya and then demonstrates the Substance 3D Painter workflow using the same UDIMS. Substance products have great integrations with most DCCs making it super-simple to do things like a UDIM workflow between 3D Painter and the final render.
