Blender Internal. Edge post processing showing as see though I've been having an issue with a few models I've been working on that include the edge post processing option turned on.



For some reason some edges can be seen through certain polys. 

As you can see on the head of this model you can see the edging that is suppose to be on the other side. I've tried inverting the faces, deleting the faces and re-creating them but it doesn't seem to work. Is there any other option anyone knows besides re-creating that entire section of the mesh?

Thank you!
The reason the edges on the back are outlined is because some pieces of the mesh in front are assigned to transparent materials.
