Why is this happening and how do I fix it? I'm still new and following this anvil tutorial but the texture is stretching over one edge and also sort of looks like I've put a seam where I haven't. It's fine on the other side and both sides are clean blue in the UV map on the right where the edge is selected

Bad side Bad Side Good side Good Side

The distortion in your unwrap may be caused by:

  • modifier options: some modifiers (e.g. solidify) can add som distortion to your unwrap
  • geometry errors: for example duplicated vertices or overlapping faces
  • uvs are not relaxed enough

So, first of all check your geometry. If your model is perfect, then you have two options:

  • unwrap again the faces which have the distortion
  • pin the borders of your shells and update the uv coordinates (a pinned vertex will keep it's position also if you try to unwrap the entire model)

I would suggest to apply the last option, and to do that:

  1. in UV/Image Editor select the border edges of your shells and press P to pin these vertices (now are red colored) enter image description here
  2. select all the shells (with A for example) and then press E, so you will update the uv coordinates for all vertices except the pinned ones enter image description here
  • $\begingroup$ Hey, thank you for replying but unfortunately after trying all your suggestions the weird distortion is still there, assuming I did them right. I did manage to fix it by deleting half and using the mirror modifier again, not a great fix which is why I didn't put it as an answer but at least it worked $\endgroup$
