Unexpected behavior - Painting across UDIM tiles not happening

I've posted a week ago about this issue, sorry for the repeat, but if I don't squeak, this wheel falls off. I'm in the Trial version, the doumentation is clear enough, as is the video tutorial on working with UDIMs, new project> link to fbx> enable Preserve UV tile layout, link to textur maps, I should see all my UDIM tiles under a single Texture Set, they're each in separate ones. The tiles map correctly to teh mesh when I assign them, but I can't well paint across them.

 

I have a perpetual Mari 2 license, need to move on, but this product not featuring tech support, I'm being directed to the forums and read that the team closely monitors for issues. It's been a week, not exactly encouraging for prospective converts. Thanks for any ideas.

Wow, the silence broken, thanks for that, interesting what you say about color id needing to be set in ZB. I'd been exporting in fbx, didn't think to try obj, much less pasing through ZB to assign same color id to each UDIM. I'll give that a whirl. Thanks again.

Seems to be an ongoing issue with folks looking but no feedback, same with my post from yesterday.  

 

SO I can tell you in order to get your figure UDIM tiles to be under one "umbrella" in the stack you need to first, if you have ZBrush, go in to that and reassign all the polygroups you want in that umbrella to one color and then reexport the obj.  

 

Example, if you have a human figure and want to paint across seams from say the head to the torso or from the torso to the limbs like the arms you need to make sure they share that same color ID.  You won't loose your UDIM set up, it's just assigned the same color ID.  I'm pretty new to all this but I THIHK I have that figured out at least but my issue was that I'm experiencing either a shadow issue and it LOOKS like it's not blending over the seams or there is a bug in SP!
