I have a disc where all the black dot points for every slice are in sync, except the one circled in red in the picture above. How can I get that one back into sync where it should be on the face of that slice?
It usually means that it’s number of vertices is different compared to the other faces. If you add a vertex to one edge (i.e by subdividing the edge), the dot in the centre of the face moves towards the extra vertex.
The one I made has one extra vertex so it tells me: Verts:4/24 (4 Verts selected out of a total of 24 on the object. It should, of course, have only 3, being a triangle.
