pymel.core.modeling.unfold¶

unfold(*args, **kwargs)¶

None

Flags:

Long Name / Short Name		Argument Types	Properties
applyToShell / applyToShell		bool
	Specifies that the selected components should be only work on shells that have something have been selected or pinned.
areaWeight / aw		float
	Surface driven importance. 0 treat all faces equal. 1 gives more importance to large ones.
globalBlend / gb		float
	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
	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
	Maximum number of iterations for each connected UV piece.
optimizeAxis / oa		int
	Degree of freedom for optimization 0=Optimize freely, 1=Move vertically only, 2=Move horzontally only
pinSelected / ps		bool
	Specifies that the selected components should be pinned instead the unselected components.
pinUvBorder / pub		bool
	Specifies that the UV border should be pinned when doing the solve. By default only unselected components are pinned.
scale / s		float
	Ratio between 2d and 3d space.
stoppingThreshold / ss		float
	Minimum distorsion improvement between two steps in %.
useScale / us		bool
	Adjust the scale or not. Flag can have multiple arguments, passed either as a tuple or a list.

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]' )
