can't get more than 1 udim tile in a texture set

I use 8.3 and watched quite a few tuts and online information. They all come up with a texture set with more than 1 UV tile. I want to be able to paint across the tiles. I've got 1 obj file and only 1 serie of 4 base color udims. creating a new file, import the obj an UV tile workflow with Preserve UV tile layout checked. I've tried with and without importing the base color texture files, but always I get 4 texture sets with 1 UV tile per texture set. That way I can't paint across the tiles. What am I doing wrong? Any help is appreciated.

regards

René

Hello René,

 

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. If Substance 3D Painter creates 4 texture sets, most likely the mesh has 4 different Material ID.

 

May I suggest you to check in your 3D software that your mesh has only one material applied ?

 

Also, make sure you checked the UV tile workflow while starting a new project.

Ah, my obj and textures are exported from agisoft metashape. Now I think that's where the problem comes from. Now I'm looking into a way to correct this in C4D and then import it in Painter.

Thanks Cyrill for the clarification.

slowly but surely it begins to make sence to me.

I've opened the obj in cinema4D and with Arnold I could turn the textures into udims. After saving I could import the obj in Painter and loaded only 1 textureset with 4 UV tiles.

When you mentioned Material ID I tried something else and that works as well and is a lot faster: I edited the .obj file and got rid of all .mtl lines. Works like a charm.

So thanks for your post.

Regards,

René van Gageldonk
