First time here at Blender exchange.
So this is how I marked the seams in this test model but when I go to UV unwrap it this is what I get:
Its like regardless of what I do this part here never gets separated into its own island and I dont know why:
I'm obviously not an expert but I've UV unwrapped other models in the past and never had this problem, I've tried different things but so far I haven't been able to pin point the problem, so I'm sure I'm just doing something incredibly silly.
Any help? Thank you!
EDIT: Okay so I just found that I had a couple of vertices really close together and they seemed like they were one so there was some edges that werent marked as seam! But, now that I've fixed this when I UV unwrap it even though it's a lot better I still have this:
Why is it stretching like that there?
EDIT 3: What I'm really trying to understand here is that in this example: Why are those vertices appearing in the wrong position, and why if I manually try to move them in the correct position the other vertices in the other island get moved too even though they are in a different island?
