I’m having difficulty unrolling this surface. The goal is to flatten this shape so that it can be built physically out of fabric. I tried to cut it into quadrants (see image) and then doing a flattensrf, that wasn’t working. I also did unrollsrf, but the command line kept saying 'unrolling doubly curved srfs will produce inaccurate results.
