I import an 3D object from OBJ file, and the relative .mtl and map image are loaded automatically.
My UV map image is messy.
I want to use other unwrap way or make seam by myself. But when I use other unwrap way, only triangle mesh change, UV map is still the same, so object renders incorrectly.
I am not good at Blender... Is it possible to move UV map with the triangle mesh, and generate new UV map?
