I joined a couple of edges together and when I run “ShowEdges” it tells me that there are no naked edges. However, when I go to rendered view I see creases in the surface (see image).
The middle crease doesn’t matter, I didn’t set G2 continuity there on purpose. I am however worried about the creases that are highlighted by the red elipses. Is my surface actually creased (i.e. bad) or is it just a rendering bug showing?
