This opens the Relax Tool dialog.
3. Choose the relax metho d . Three are available
from the drop-down list:
•RelaxByFaceAngles
•RelaxByEdgeAngles
•RelaxByCenters

this most often gives the best results.
4. Set the other options and then click Apply.
As the relaxing progresses, a message appears
showing you which frame is being processed. A
frame is equivalent to an iterat ion.
The appropriate method and other settings
to use depend on a variety of conditions,
including the complexity and topology of the
mesh, so experimentation is usua lly required.
Relaxing is undoable, so if one method doesn’t
work, undo and try a nother.
To use Relax to fix overlapping faces:
This procedure provides general guidelines for
resolving overlapping texture faces. It might not
work in every case, but it should give you a starting
point for correcting most situations.
1. Open the Edit UVWs dialog and in the
Selection Modes group, click Face Sub-object
Mode.
2. From the Edit UVWs dialog > Select menu,
choose Select Overlapping Faces.
Only the overlapping faces are selected.
3. Click Expand Selection to select faces
surroundingtheoverlappingfaces.
Thisgivestheoverlappingfacesalargerarea
in which to spread out.
4. From the Tools menu, choose Relax Dialog.
5. On the Relax Tool dialog, set Stretch to an
intermediate value. If the overlapping is
considerable, use 0.5 or higher. If it’s relatively
small, try 0.1 to 0.3.
6. Click Apply.
If this seems to be helping, continue clicking
Apply until the overlapping is resolved. If
not, undo (

Face Angles instead, or increase the Amount
value, or change the Stretch va lue, or use
combinations of the above.

Relax B y Face Angles—Relaxes the vertices based
on the shape of the faces. It tries to align the
geometric shape of the face to the UV face. This
algorithm is mainly used to remove distortion
