Can Blender create seams on its own?

Hello,

So I decided to try and UV map my first character with Blender, but I had an issue that took me a while to fix.

I marked my seams and unwrapped my mesh, but it seems like Blender created a seam on its own when it wasn’t necessary, because of this my UV map was awfull at first.

After a while, I thixed it by using the “clear seam” tool on some edges, but I am sure that I never placed any seam on this part so it shouldn’t have been a seam.

So could I have done anything wrong or did Blender just has a bug or made a seam on its own?

Here is what I had :

Textured on the mesh


And on the UV map


Check for double vertices, correct normals, and scale/rotation applied.
A file would be great for as to analyze.

So sadly I can’t provide you any “bugged” file, since I fixed it, but I checked for doubles, and it don’t seem to be any.
I didn’t take the scale, rotation or normals of the mesh in consideration while UV mapping, it may have been the problem.

Or maybe it was just a problem of selection during an unwrap… But I don’t really know…

I can still send you the file of the model I fixed, the issue was with the left front leg.
