Whenever I try to use the BSurfaces addon I can't add a surface, all I get is an error saying
The selection isn't valid
it was working on one file, but it never worked on anything else since. What did I do wrong?
I am using Blender 3.4.1
This has been killing me for days and I really want to do repto again.
I have spent hours searching for the answer but nothing comes up.
Please tell me if there's something I'm supposed to do first.
