    If you set up your figure to export as an OBJ with surfaces, it will import into Blender (use Keep Vert Order and Polygroups), and you go into edit and select all the verts, you will see that the UVs are in UDIM tiling.  Only the 0-1 space has a grid.  You can watch this video.

    and it will show you how to set up in Cycles so that you can put texture images on all of the figure and have the textures on its appropriate UDIM UV space.

    While this doesn't cover actual painting, you can probably see how you could add an existing texture you may have made elsewhere, or create a texture image and assign it to a particular map in the UDIM lineup that you can then paint on.  You can also layer different kinds of surface-type maps over each other.

    Hope this helps.

    This may be helpful for Blender painting on UDIM.

    Chris,

    Awesomeness. Thanks much. I never knew that about UV maps. Looks like there was some talk online of some beginning UDIM support in Blender a few months ago, but I guess it's still in its infancy. Apparently ZBrush already has UDIM support. But since I recently decided that ZBrush is pretty much banned from my computer (it's far too painful to use), I guess I'll have to go the Blender route.  

    That will be awesome when D|S gets its internal support for Blender with a GoBlender function and all this stuff is automatic... smiley

    Just sayin'... smiley

    The below is not an in-depth how to but to let you know it can be done.

    The old legacy stamps in the prior non PBR versions of 3DC are gone.

    Now you create your stamps using the Smart Material editor and using "From Camera" projection.

    Create a new smart material adding your tattoo image to the color channel. If you are unsure on how to set the roughness / glossiness  and metallic channels, before you apply your tattoo turn off all  roughness / glossiness  and metallic channels by disabling the 3rd sphere icon (gray) in the top tool panel of the main UI.

    You can create a new folder and name it "Stamps" to put all your From Camera smart materials there to keep things tidy.

    Not sure why you are getting the gloss in your imported image.

    So interested in checking out the Decal mode.  I created a parented one to Dusk.  Not showing up regardless of how many of the images I cram into each drop down image nodes.  So I'm apparently doing something wrong unless this doesn't support figures that are non DAZ figures?

    FWIW and IIRC:

    Decals don't show up unless you're in Iray view mode or do a render, if that helps. Most people spend a lot of time in Texture Shaded view, but since decals are done in the Iray engine itself you have to get that involved.
