Automatically untangles and evens out
the spacing between UV texture coordinates. You can choose to pin
the border UVs so they remain in the same position while relaxing
other UVs, or pin the selected or unselected UVs while relaxing
any other UVs.
Edit UVs > Relax > 
Pinning
Use the following options
to relax only selected portions of the UV shell.
- Pin UV border
-
Turn this option on to
maintain the position of the border UVs. This is the default.
Pin UVs
Selet which UVs to pin.
- Pin selected UVs
-
Turn this option on to
maintain the position of selected UVs. For example, if you want
more texture space for an area on a face with very dense UVs, you
could select these UVs, scale them up, pin them, then relax the
rest of the UVs to eliminate any overlapping you may have introduced
during the scale.
- Pin unselected UVs
-
Turn this option on to
maintain the position of the unselected UVs. This option is useful
for relaxing only the selected UVs.
Edge weights
Select
how the UV relax operation affects edges.
- Uniform
-
Attempts to make all
of the edges the same length. This is the default.
- World space
-
Attempts to retain the
original world-space angles (subject to the restrictions of the
pinned border).
- Maximum iterations
-
Enter the number of relaxation
iterations that will be performed on the UVs—ideal UV relaxation
is subjective and iterative.
