UV Triangle Select Bug

[Pte Jack]

I have overlapping mesh in an object and need to be able to select and paint on the same texture. Is this a bug or how would I select the lattice to mask it out or paint it without affecting the mesh beneath it?

I have the UV select set to Triangle select, and it doesn't matter what select mode I select...

Happens on both the 3d and 2d viewer... and it doesn't matter how close I get to the object to attempt the select.

This is in SP2 2.5.0 build 1490

First of all, you shouldn't even lay your UV layout in this layout, if you're going to paint the grills and the one bottom on separate colours. Unsew those UV faces for the grills and place them either in a different shader, or move them elsewhere in the same UV layout.

Unfortunately, this is the way the game I'm painting for reads the UV layout, I personally would never overlay mesh in a UV layout like this if it was one of my own. However, I need to be able to paint this the way it is. All one texture.

Now, yes, I might be able to split it out if I assign it to a different materials before bringing the model into SP but if SP worked properly and selected mesh according to the UV Layout, if I select mesh on top of mesh on a UV, I should not be able to select underlying mesh when I select the top layer in the manner I'm selecting it (especially when I select from the 3D view and have no underlying mesh exposed.)

As far as I'm concerned this is a bug that needs to be fixed and has always been a peeve for me working with this software. Constantly having to go back and repaint models that bleed through to areas that it shouldn't (even when properly masked).

You could add MaterialId and mask out the top. Or even better, make all masks with MaterialId instead of selecting triangles in Substance Painter.

Yes i could, but that is extra work added to the work flow. I should just be able to select the mesh I want. Period. There should be no bleed through.

You will have bleed because they overlap each other. Unless you use 2 materials. Or if both parts have very similar looking texture.

Even if you use MatId there will still be bleeding. What game have uv layout like this?

Yes i could, but that is extra work added to the work flow.

Shouldn't take more than 1 minute.

SCS - ATS and ETS2. This is one cabs of their game models. We are allowed to repaint, not change the mesh (Copyrights and all).
