I am trying to use the texture paint cloning tool to cover up a seam. What I am expecting the cloning tool to do is clone the texture exactly, however, I find that it paints it differently on the mesh depending on the viewing angle and on how close I am to the mesh.
In the image below there are 2 objects. I am painting to the object on the right. If the cone tool would work as expected, the texture (UV test grid) on the right object should match up with the texture on the left object along the middle.
I discovered that if I am in ortho view and I paint the texture, it aligns perfectly. Why does this not work in perspective view? Ortho view is very difficult to use - parts of the mesh block areas I am trying to paint. How can I paint in perspective view and get the textures to align?
