Imported Mesh Maps not working with UDIMs

Question

I have a mesh set up to use UDIMs.I baked the mesh maps (AO, curvature, position, and wsNormals) in Designer.I then imported the model and mesh maps into Painter.The model is correctly set up for UDIM work flow - it has a single Texture Set and all of the UDIMs appear in the 2D view correctly.The imported baked textures also correctly display as UDIM textures in the LibraryHowever, when I try to apply an imported baked texture as a mesh map, it incorrectly copies the 1001 UDIM onto every other UDIM slot.This behavior just appeared recently.-----------Substance 3D Painter, version 7.4.1Build 1418 - 7c8c2fc4fdff1f8e3d4000066a023321898b6277-----------

Hi, this might have to do with the way you set up the project. If you didn't enable UDIMS when you created it, you will have to create a new project.

Create new project.
Under UV Tile Settings (UDIMs), check the box for "Use UV Tile workflow"
Select "Preserve UV Tile layout per material and enable painting over tiles"

The baked textures as they appear in windows explorer

the baked textures correctly displaying in Painter's library

The model (left) and UDIMs (right) correctly displaying in Painter

The applied AO bake on the model (left) and UDIMs (right). As you can see, the 1001 texture is being used for all UDIMs.
