When I try to do a full flattening of a surface I often get areas with extreme squishing, looking like wrinkles. Usually if I redo the cuts in slightly different ways (e.g. adjust the spacing between cuts, extend the cuts farther onto the lateral surface, etc) I can get the flattened surface to come out looking smooth. Sometimes it takes several attempts (with several hours of computation for each attempt) to get it right. Has anyone else noticed this, and has anyone attempted to improve the flattening algorithm?
