I'm trying to select uv edges on my lowpoly model, but the option in the uv editor for selecting contour edges does not work on those types of models. It seems to work fine if you have an extra edge loop between seams, but otherwise it just selects everything. These models basically have the same uv map, the other one just…
It does that when you have triangles near the seams, or very very few verts. Basically contour selects everything, shrinks the selection once, and then inverts the selection for the result. So if there's not enough vertices to support that one shrink selection command then it will unselect everything, which will leave you…
