Blender Tidbits #1

I am working on the BSoD character animation tutorial and ran into something wierd. As I was shaping the face I noticed that the “skin” was sticking to one of the vertices even though it shouldn’t have been. I also noticed that there were two black lines sticking out of the model at two related vertex points. After further investigation, I found that there were double vertices (on top of each other) that were causing the problem. I selected all the vertices in EDIT MODE and hit the REM DOUBLE button under MESH TOOLS menu. After the doubles were removed, everything was corrected.
