Substance painter Issue with UDIMs

cghunt3d

Hey, I've imported my model into substance as usual and when I try to bake the details from my high poly model it ends with the result in the first image only baking parts of it randomly, has anyone seen this before?

also when I use the normals that I baked in zbrush parts of the Uv shells are inverted too (Second image).

Any fixes would be greatly appreciated.

Make sure Substance Painter or Designer recognizes your model as UDIM. Looks like it doesn't.

It's actually pretty picky and unforgiving to even slightest UV mismatch in one of the tiles.

 

Anyway they are both pretty bad  for  UDIM model texturing since you could paint/work with only one tile at a time. Nothing to paint across uv tiles seams .    Last time I tried at least.
