How do I merge vertices into another polygon? I'm new to Blender and I'm trying to make a low-poly wolf, but the problem I'm having is when I have to create a new polygon in between some vertices. I can't, for the love of me, figure this out. I tried to press ALT+M=>At Center, but that just jumbles up the vertices.
To create a new face (polygon), select the vertices or edges with Shift and right click, then press F.
