I have a big problem with unwrapping model (tight pants) in blender (look the picture 1).
I marked seams but result of unwrapping looks weird because some vertices are not on their place (look the picture 2), because of this some faces on model do not look good (look picture 3).
Can someone help me?
I tried Removing doubles and Select non manifold but it does not help.
In Edit Mode I would try CTRL and right click to trace out your lines, Mark as needed and use live unwrap. And keep in mind that remove doubles can break a mesh just as easy as it can fix it.
Funny thing is, is that it’s actually not just UV but UVW. W being an extra alpha channel used for depth mapping. (As UVW comes before XYZ, and representing the corresponding normal surface topology of objects represented by XYZ.) However since the W component isn’t always used, it typically gets shortened to the first two. How I know that bit of 3D trivia? Who knows? But feel free to look it up.
