Axis setup

You need not set up anything, except that the mirror axis of either your UV map or mesh is not X but Y.

Case 1. Both UV and mesh are mirrored along X axis (Default)

Case 2. Both UV and mesh are mirrored along Y axis

Case 3. UV is mirrored along X axis, but mesh is mirrored along Y axis

Open Wings (Obsolete)

This function is similar to the Expand Mode except that the original UV map is scaled down to half size.

As the usage of this function is very limited, it will be removed in the future release. If anyone hopes this function will remain, let us know.
