Use the Auto Seams command to let Maya automatically identify and select the best edges on the selected mesh(es) or UV Shell(s) to act as a seam.
Auto Seams Settings
- Seams
-
Determines whether to just select the appropriate edges or perform a Cut UVs operation on them. Defaults to Cut.
- Shell Splitting Tolerance
-
Determines the likeliness that existing UV shells will be split into new shells when cutting. Setting this to 0 prevents the creation of new shells entirely.
- Connect Holes
-
Attempts to fill holes in the UV shell, which can help reduce distortion. Defaults to on.
