We have for the same model, two very different vertex counts (triple the number of triangles in jpct versus the unique vertex count which is typically less than the number of triangles in any given model), while retaining the same number of triangles, between jpct and 3ds max. But when we create our SkinData, we use only the number of unique vertices. Now we're thinking that we should be using the number of vertices in jpct. Did that make sense to you and do you agree?
