Relax Tool Dialog 895
This opens the Relax Tools dialog.
3. Choose the relax method. Three are available
from the drop-dow n list:
•RelaxByFaceAngles
•RelaxByEdgeAngles
•RelaxByCenters
ThedefaultmethodisRelaxByEdgeAngles;
this most of ten 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 iteration.
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 usually required.
Relaxing is undoable, so if one method doesn’t
work, undo and t ry another.
To use R elax to fix overlapping faces:
This procedure provides general guidelines for
resolving overlapping texture faces. It might not
work in ever y case, but it should give you a star ting
point for correcting most situations.
1. Open the Edit UVWs dialog and in the
Selection Modes grou p, click Face Sub-object
Mode.
2. From the Edit UVWs dialog > Select menu,
choose Select Overlapping Faces.
Only the ove rlapping faces are selected.
3. Click Expand S elect ion to select faces
surrounding the overlapping faces.
This gives the overlapping faces a larger area
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 (CTRL+Z) and try using Relax By
Face Angles instead, or increase the Amount
value, or change the Stretch value, or use
combinations of the above.
Interf ace
[rel ax method]—Themethodusedtorelaxthe
texture vertices. Choose f rom the drop-down list:
•
Relax By Face Angles—Relaxes the vertices
based on the shape of the faces. It tries to align
thegeometricshapeofthefacetotheUV
face. This a lgorithm is main ly used to remove
distortion and not so much to remove overlap,
and is best suited for simpler shapes.
•
Relax B y Edge A ngles—This default method
is similar to Relax By Face Angles except that it
uses the edges that are attached to the ver tices
as the shape to match. I t typically works better
than Relax By Face Angles but tends to take
longer to reach a solution. This method is
bested suited for more complex shapes.
