將你個Model cut 間geometry一半(UV ok 個半補留),
1, then Mirror Geometry,choose mirror direction.
eg. +x,-x,+y,-y.......... or
2, Select the half geometry, duplicate with scale -1 with one direction, select both, combine, then final Merge Verticles, Merge Multiples or use Merge Edge Tool.
Good luck

then Cut UVs,
In one of your view, e.g. perspective.

Go to UV texture editor. Select Shell,
then you can move the UVs. Scale your UVs,
