HELP WITH SUBSTANCE HELP!!!

Hello.. something weird is happening here
I imported a model I did in maya into substance painter and one of the geometry of my model is not displaying correctly the material in the substance viewport... Uvs for this model are organized in 3 udim .. everything is fine except for this geometry. I did the uvs for this piece as I did the others but as soon as I apply a smart material I get weird artifacts all over the component and I don't really understand why.. I imported this model unchecking the option - create texture set per udim tile-

I tried everything and nothing, then I imported the component by itself  CHECKING create texture set per udim tile and it actually worked so I assume the problem arises in the moment I uncheck this guy.. so I believe I could go on and make the texture for this component separately but I don't really like this I want to be able to see how the whole model will look like.. Here some screenshot 
this is how the model is in maya (I exported the smoothed version)



heres the UDIMS 



HERES THE PROBLEM! as u can see all those weird artifacts affecting my mesh. T_T



Heres when I import the mash alone IT DOES WORK CORRECTLY (create texture set per udim tile is checked)


ANY HELP PLZZZZZZZZZ?
thx

have you set up different material id's for each UDIM?

i dont know about UDIM workflows but most of the time if I see an issue like this it is because I had an extra UV set. There are a few common operations in maya that the default tool settings will create a new UV set, so they can sneak in there without you realizing it.

Also, ask for help smartly. Don't use all caps. Be calm.

That's what it's supposed to do.


If you don't create a unique texture set per UDIM they'll all get the same information applied
