polyFlipUV([caching=boolean], [constructionHistory=boolean], [createNewMap=boolean], [flipType=int], [insertBeforeDeformers=boolean], [local=boolean], [name=string], [nodeState=int], [uvSetName=string])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

polyFlipUV is undoable, queryable, and editable.

Flip (mirror) the UVs (in texture space) of input polyFaces, about either the U or V axis..

Return value

stringThe node name.

In query mode, return type is based on queried flag.


caching, constructionHistory, createNewMap, flipType, insertBeforeDeformers, local, name, nodeState, uvSetName
Long name (short name) Argument types Properties
createNewMap(cm) boolean createquery
Create a new UV set, as opposed to editing the current one, or the one given by the uvSetName flag.
uvSetName(uvs) string createquery
Specifies the name of the UV set to edit uvs on. If not specified will use the current UV set if it exists.
When createNewMap is on, the name is used to generate a new unique UV set name.
insertBeforeDeformers(ibd) boolean create
This flag specifies if the polyFlipUV node should be inserted before or after deformer nodes already applied to the shape. Inserting the node after the deformer leads to texture swimming during animation and is most often undesirable.
C: Default is on.
flipType(ft) int createqueryedit
Flip along U or V direction.
0 Horizontal
1 Vertical

C: Default is 0.
Q: When queried returns an int.
local(l) boolean createqueryedit
Flips in the local space of the input faces.
C: Default is on.
Q: When queried returns an int.
Common flags
name(n) string create
Give a name to the resulting node.
constructionHistory(ch) boolean createquery
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.
caching(cch) boolean createedit
Toggle caching for all attributes so that no recomputation is needed
nodeState(nds) int createqueryedit
Defines how to evaluate the node.
  • 0: Normal
  • 1: PassThrough
  • 2: Blocking
  • 3: Internally disabled. Will return to Normal state when enabled
  • 4: Internally disabled. Will return to PassThrough state when enabled
  • 5: Internally disabled. Will return to Blocking state when enabled

Python examples

import maya.cmds as cmds

# Create a poly sphere with default UVs.
cmds.polySphere( n='sph' )

# Flip uvs on all faces of the sphere shape.
cmds.polyFlipUV( 'sphShape.f[*]' )
