I modified the neckline of this shirt. But this still has some bad points.
I usually tried to modeling 3d objects in the small number of polygons as much as possible. But the number of them must not be too small. Too low polygonal clothings become inconvenience at the figure bending. So, I divide the polygons by double finally.
But I don’t know why the map was warped when the polygons are doubled.
Please overlook, the map has somewhat wrong points, though…
