Paints in multiple places at once on the mesh

[sw2349600]

Hi, 

New to Substance Painter. Just wondering why when I paint, it paints in multiple spots on the mesh instead of just one spot? I have mirroring turned off,  I have "UV" set in the Alignment on the brush setting and in the new project I have Use UV Tile Workflow checked. 

From blender it's just 1 material and 1 mesh. Do I need to assign more materials or set it up somehow so it doesnt do this? Or is this something I can fix in SP? 

Thanks!

Hi @sw2349600,

My first guess would be overlapping UVs. Can I have a look at your UVs ?

Keep me posted.

Thanks, how do I show the UV map in SP? I only see the textured version (attached).

Here's the map in Blender though, it's hard to tell if it's overlapping. But would SP's uv map look different?

No problems, it's textured but those are still your UVs. It seems they're indeed overlapped. Basically, the UVs are the 3D model unfolded in a 2D space. Therefore, if the UVs are overlapping, it's as they're in the same space, creating the issue you're facing.

You'll need to rebuild the UVs and reimport the mesh. You can take a look at our tutorial about Model Preparation for Substance 3D Painter, or (if you don't want to bother with UVs) you can use the Auto-Unwrap option.

Just make sure to switch the Seams parameter to Recompute all in the Options.

Best regards,

Thanks so much for your help, it seemed to work before trying your method by not including the blender material. I had auto unwrap on before when it wasnt working. 

But good to know about your guide, I will keep this in mind. 

Cheers!
