two textures: painting on one of them while the other is still visible (2.8) I have a model with two UVs and two textures: first set is a projected UV with paintover from Photoshop and second UV is a generated UV to paint on top. They're mixed using the Alpha of the second texture.

UVs:



Textures:



Result in Lookdev mode:



I want to be able to paint on the second texture while seeing the first one and sampling colors from both first and second. Is this possible?

At the moment when I switch to paint mode and make several light brush strokes my first texture looks very dark and brushstrokes look like they're opaque. When I switch back to Object mode everything looks like it should.
Have you tried to turn off overlays in LookDev mode?
