UDIM support has recently been added to Blender 2.82 Alpha. This is very useful for the Daz Importer, because the UV coordinates in Daz Studio are arranged in UDIM tiles, at least for the Genesis 3 and 8 characters.
Since there are several skin materials, editing them consistently is tedious and error prone. The Mini Material Editor addresses this to some extent, but its power is quite limited. With UDIMs we can combine all skin materials into a single one, which we can then edit using the powerful node editor.
The textures nodes have been changed like this. A "T_" has been added in front of the texture name, extension = Clip, and source = Tiled.
In the UV editor, we can now see the tiles of the tiled texture. Notice that the tile labels equal the old material names.
