unfold(*args, **kwargs)

None

Flags:
Long name (short name) Argument Types Properties
applyToShell (applyToShell) bool ../../../_images/create.gif
 
Specifies that the selected components should be only work on shells that have something have been selected or pinned.
areaWeight (aw) float ../../../_images/create.gif
 
Surface driven importance. 0 treat all faces equal. 1 gives more importance to large ones.
globalBlend (gb) float ../../../_images/create.gif
 

This allows the user to blend between a local optimization method (globalBlend = 0.0) and a global optimization method (globalBlend = 1.0). The local optimization method looks at the ratio between the triangles on the object and the triangles in UV space. It has a side affect that it can sometimes introduce tapering problems. The global optimization is much slower, but takes into consideration the entire object when optimizing uv placement.

globalMethodBlend (gmb) float ../../../_images/create.gif
 

The global optimization method uses two functions to compute a minimization. The first function controls edge stretch by using edges lengths between xyz and uv. The second function penalizes the first function by preventing configurations where triangles would overlap. For every surface there is a mix between these two functions that will give the appropriate response. Values closer to 1.0 give more weight to the edge length function. Values closer to 0.0 give more weight to surface area. The default value of ‘0.5’ is a even mix between these two values.

iterations (i) int ../../../_images/create.gif
 
Maximum number of iterations for each connected UV piece.
optimizeAxis (oa) int ../../../_images/create.gif
 

Degree of freedom for optimization 0=Optimize freely, 1=Move vertically only, 2=Move horzontally only Flag can have multiple arguments, passed either as a tuple or a list.

pinSelected (ps) bool ../../../_images/create.gif
 
Specifies that the selected components should be pinned instead the unselected components.
pinUvBorder (pub) bool ../../../_images/create.gif
 
Specifies that the UV border should be pinned when doing the solve. By default only unselected components are pinned.
scale (s) float ../../../_images/create.gif
 
Ratio between 2d and 3d space.
stoppingThreshold (ss) float ../../../_images/create.gif
 
Minimum distorsion improvment between two steps in %.
useScale (us) bool ../../../_images/create.gif
 
Adjust the scale or not.

Derived from mel command maya.cmds.unfold

Example:

import pymel.core as pm

# Create a sphere and select it.
pm.polySphere()
# Result: [nt.Transform(u'pSphere1'), nt.PolySphere(u'polySphere1')] #
# Optimise the position of some Uvs
pm.unfold( 'pSphere1.map[189:398]' )
