This isn't my code, it came from someone at Softimage. To my shame I can't
remember who it was. Apologies to them.
mFixUVs_Execute selection(0)
Sub lmFixUVs_Execute( InputSelection )
' ---[ Retrieve Object & Parameters
]-------------------------------------
Set oClsProp = InputSelection
Set oCluster = oClsProp.Parent
Set oX3DObject = oCluster.Parent.Parent.Parent
aIndices = oCluster.Elements.Array
aElements = oClsProp.Elements.Array
Dim aFixed()
Redim aFixed(2,oClsProp.Elements.Count-1)
'
iUBound = oX3DObject.ActivePrimitive.Geometry.Samples.Count - 1
Dim aSamplesIdx()
Redim aSamplesIdx(iUBound)
Set oFacets = oX3DObject.ActivePrimitive.Geometry.Facets
id = 0
For Each oFacet In oFacets
For Each oSample In oFacet.Samples
aSamplesIdx(id) = oSample.Index
id = id + 1
Next
Next
'
For i = LBound(aElements,2) To UBound(aElements,2)
idx = aSamplesIdx(aIndices(i))
aFixed(0,idx) = aElements(0,i)
aFixed(1,idx) = aElements(1,i)
Next
'
oClsProp.Elements.Array = aFixed
End Sub
