At work, I’m editing an order of contractor assets. Every model comes in with UVs and textures, but it’s my job to make sure they’re up to a certain standard before integration. While doing one edit in particular, I marked a seam with the intention of using it only to simplify my selection process (Select Linked w/ Limit by Seams).
However, when I added the seam, the UVs seemed to auto-unwrap. I wasn’t broken up about it at the time because it wasn’t imperative that I mark seams, but I thought that it was very strange. Now I can’t add seams to any mesh, in progress or finished, without the UVs distorting.
I’ve never seen this before, and I’m hoping that it’s just some option I turned on and not a major bug. Does anyone have any ideas?
