pymel.core.modeling.polyOptUvs

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.
frozen / fzn bool  
   
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 of 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 improvement 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]' )
