Issues after updt v9.1.1

Question

I don't understand what's happening with the UVs in Substance Painter since the last few updates... I am able to select UVs of other parts from the Texture Set List but unable to make them all appear at once in 2D view, why?

This is how the UVs are in Maya.

Also, I am getting baking issues with this model how do I fix this?

Hello @32070099,

Thanks for the message, and nice robot you have here.

To be fair, Substance Painter has a consistent hierarchy Since the support of UDIM workflow : Texture set > UV tile

A texture set is defined by a Material ID. Each time Substance 3D Painter finds a new Material ID, it will create a new texture set, and you can't paint across texture sets. If Substance 3D Painter creates 4 texture sets, most likely the mesh has 4 different Material ID.

If you don't have 4 different Material ID, but you do have 4 different texture sets, make sure that you don't have the (legacy) UDIM workflow activated when creating a new project.

Regarding the legs issue, UVs are overlapping. Make sure that each UV island is separated from the others. In addition, I advise you to correct the Texel Density of these legs.

Regards,
