Solidify modifier causes black artifacts on mesh I'm new to Blender and I've got a problem while using the solidify modifier.
I'm creating a Minecraft character using a rig and I want do a 3D-Head with the solidify modifier but it looks like this:



The sides of the solidified faces are glitching; they should have the same color as the top part

[EDIT]
I solved the problem; If I select every face seperatly and use Remove Doubles UV it works.
Solution
I switched into Edit-Mode and selected one face that was wrong. Then I pressed Spacebar and used Remvoe Doubles UV. Now the incorrect face was correct and I continued with the other faces.
