I am encountering an question and issue when modeling subdivision surfaces in Blender when I want there to be a sharp corner at a vertex. From what I recall, I could do this in Cinema 4D fairly straightforwardly by weighting a vertex. However, in Blender it seams that one can weight a “crease” but I don’t see how to weight a vertex. To me, this seems like something that an amazing program like Blender should be able to do, so hopefully I am just missing something. Here are some illustrations to show what I mean:
Illustration A shows a bunch of polygons with a subdivision surface modifier applied. Note that all corners and creases are subdivided and smoothed out.
Illustration B shows the same shape, only on two of its edges the edge creasing weight has been changed from 0 to 1. This results in a sharp edge crease at those edges. That is useful for some things I suppose, but that is not what I am looking to do.
Illustration C shows more what needs to be done. At point 1, I want the subdivision surface to come to a sharp corner (along the red lines). In other words, I do not want the corner to be curved as is there now. I don’t want any edges to be creased either.
Is there a way to keep all subdivisions on the shape except be able to weight that vertex (1) so it comes to a sharp corner at that point? I really need a sharp corner at that point.
Thank you ever so much in advance for your help.
