Blender Cycles - Transparency Issue While working on the texture of a model I found a problem with my render.


As you can see here the mesh outline for the eyebrow can be seen and everything I've tried, I just can't seem to fix that one thing.

I used Blender Cycles and Blender 2.78.



Edit: Packed textures in .blend file.
Well I am stumped. It doesn't seems to have a solution apart from pulling the eyebrow geometry slightly away from face. It seems the intersection created by the 2 meshes is causing the black lines.

Other things I've tried:


Alpha Premultiply/Straight settings
Render bounce and transmission settings
Turning off all ray visibility expect for camera rays
Texture clipping settings
