viewport painting issue

snake85027

I have a basic box that I made and I then mirrored it , so the uv are overlapping.
I then started using the Viewport Canvas tool and for some reason when I go to paint on the model it doesn't paint where my cursor is, it paints way off from it...

Does it now work well when it is painting on a object with overlapping uv?

for example on this image I am trying to paint but it actually paints on the inside of the model.

When you use Symmetry, the UVs are overlapped. So then Viewport Canvas is trying to paint on both UVs, or whichever one is on top.

To prevent this, use the UVW Unwrap modifier to move the overlaps 1 unit over, collapse the stack (not required, just good housekeeping), and try painting again.
