Part of creating good topology for CheckMate Pro v2 subdividable models is to avoid T-vertices, the convergence of edges in a T formation, unless they are absolutely necessary for the flow of the model’s shape. T-vertices, or T-verts for short, when used incorrectly, will halt edge flow and cause poor subdivision.
Any vertex with only three edges could be consider a T-vertex; the crossbar of the T doesn’t have to be straight across. You can use them when there’s no better solution, but it is best to avoid them as much as possible. Read More
