pymel.core.modeling.polyOptUvs

static modeling.polyOptUvs(*args, **kwargs)

Optimizes selected UVs.

Flags:
Long name (short name) Argument Types Properties
applyToShell (applyToShell) bool ../../../_images/create.gif
 
Specifies where the whole object or just shells that are selected or pinned should be affected.
areaWeight (aw) float ../../../_images/create.gif
 
Surface driven importance. 0 treat all faces equal. 1 gives more importance to large ones.
caching (cch) bool ../../../_images/create.gif ../../../_images/edit.gif
 
Toggle caching for all attributes so that no recomputation is needed
constructionHistory (ch) bool ../../../_images/create.gif ../../../_images/query.gif
 

Turn the construction history on or off (where applicable). If construction history is on then the corresponding node will be inserted into the history chain for the mesh. If construction history is off then the operation will be performed directly on the object. Note:If the object already has construction history then this flag is ignored and the node will always be inserted into the history chain.

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.
name (n) unicode ../../../_images/create.gif
 
Give a name to the resulting node.
nodeState (nds) int ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 

Defines how to evaluate the node. 0: Normal1: PassThrough2: Blocking3: Internally disabled. Will return to Normal state when enabled4: Internally disabled. Will return to PassThrough state when enabled5: Internally disabled. Will return to Blocking state when enabledFlag can have multiple arguments, passed either as a tuple or a list.

optimizeAxis (oa) int ../../../_images/create.gif
 
Degree of freedom for optimization: 0=Optimize freely, 1=Move vertically only, 2=Move horzontally only
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.
uvSetName (uvs) unicode ../../../_images/create.gif ../../../_images/query.gif
 
Specifies name of the uv set to modify. Default is the current UV set. Common flags
worldSpace (ws) bool

Example:

import pymel.core as pm

# Create a sphere and select it.
pm.polySphere()

# Optimise the position of some Uvs
pm.polyOptUvs( 'pSphere1.map[189:398]' )
