On the side of the toe there is a change in color.

I don't know which texture it is. Whether its the normal map or the skin, I'm not sure. But when I go into texture paint mode, and select the blur tool, it barely changes when using it.

EDIT

I realized its the shape of the topology??? It goes all the way up the foot and cuts off at the front of the ankle in the shape of a seam formed by vertices on the foot

EDIT

It's also at the place where the map was separated into different sections. EG legs, arms etc

  • $\begingroup$ Hi, I don't think there were doubles because it didn't do anything :( $\endgroup$ Sep 1, 2015 at 18:38
  • $\begingroup$ Anything else..? $\endgroup$ Sep 1, 2015 at 19:07
  • $\begingroup$ It looks like you have doubles, try to move the vertices and see if they are connected or not $\endgroup$

    $\begingroup$ the normal map is causing this shading problem ( it's not in the file ) $\endgroup$

Things to check:

  • Creased? Turn on the display of creases (N > Mesh Display > Creases), then enter Edit Mode (Tab) and look for a blue line along that section. If you see the blue line, clear the crease (Edge Select Mode, Ctrl+E, Clear Crease)

  • Internal Face? Check to see if you an internally extruded face along that section. Hit Z to enter Wireframe Mode, switch to Face Select Mode, and look for a third face attached to that edge. If so, delete it (them).

  • Edge Split? Ensure you don't have an Edge-Split modifier with too low of a value (Properties > Modifiers > Edge Split)

  • Shade Flat? Select all faces surrounding the issue and hit W then Shade Smooth


I downloaded your blend and took a quick look. It doesn't appear to be any of the things I've listed, but seem to be (as you suggested) associated with the UV mapped textures. The area in question is along two non-contiguous UV segments. So, unless the pixels directly under both segments have identical colors, one would absolutely expect there to be such a discontinuity.

My suggestion is to re-project the geometry so as to avoid seams in your UV in prominent positions.
