I created a 3d human face with 'Facegen Modeller' and I opened it with Blender, trying to adapt it to my needs. Inside the eye there is a bluish/greenish oval shape. What is that? When I try to mark it as seam, the color does not change. I removed that shape in edit mode and then created it again and now it seems to be marked correctly. Am I making a mistake?



You marked those edges as being sharp, possibly by accident.

It happens when you select an edge or edgeloop and press Ctrl + E > Mark Sharp

To remove it select the edge or edgeloop in question and press Ctrl + E > Clear Sharp

    $\begingroup$ Thanks. Yeah could have happened by accident, or by mistakenly pressing some key combination or by some addon or tool. $\endgroup$ – Duarte Farrajota Ramos May 19 '16 at 16:24
  • $\begingroup$ what's sharp,in a few words ? $\endgroup$ – Marietto May 19 '16 at 19:24
  • $\begingroup$ Sharp edges are used on smooth shaded meshes to create a break on an otherwise continuous surface, think a corner or sharp edge in the surface $\endgroup$ – Duarte Farrajota Ramos May 19 '16 at 22:19
