polyMapSewMove([caching=boolean], [constructionHistory=boolean], [limitPieceSize=boolean], [name=string], [nodeState=int], [numberFaces=int], [uvSetName=string])

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

polyMapSewMove is undoable, queryable, and editable.

This command can be used to Move and Sew together separate UV pieces along geometric edges. UV pieces that correspond to the same geometric edge, are merged together by moving the smaller piece to the larger one.

Return value

stringThe node name.

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


caching, constructionHistory, limitPieceSize, name, nodeState, numberFaces, uvSetName
Long name (short name) Argument types Properties
numberFaces(nf) int createqueryedit
Maximum number of faces in a UV piece. When trying to combine two UV pieces into a single one, the merge operation is rejected if the smaller piece has more faces than the number specified by this flag.
This flag is only used when limitPieceSize is set to on.
limitPieceSize(lps) boolean createqueryedit
When on, this flag tells that the face number limit described above should be used.
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.
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

# merge them back, with the appropriate move.
