API and Offset BlendShape

[Rémi Deletrain]

Hi everyone,

I try to get offset points of blendshape with maya API.

whis pymel is very simple with this line:

----------------------------------------------------------------------------------------------------------------------------------------------------------

pmc.PyNode(blendshapeName).inputTarget[0].inputTargetGroup[0].inputTargetItem[6000].inputPointsTarget.get()

----------------------------------------------------------------------------------------------------------------------------------------------------------

whis API:

----------------------------------------------------------------------------------------------------------------------------------------------------------

#    For get MFnBlendShape

selectionList = OpenMaya.MSelectionList()

selectionList.add(blendShapeName)

bsObject = OpenMaya.MObject()

selectionList.getDependNode(0, bsObject)

bsDependencyNode = OpenMaya.MFnDependencyNode(blendShapeObject)

#    For get weights datas

attributeName = "inputTarget[0].inputTargetGroup[0].inputTargetItem[6000].inputPointsTarget"

selectionList = OpenMaya.MSelectionList()

wPlug = OpenMaya.MPlug()

selectionList.add(blendShapeName + "." + attributeName)

selectionList.getPlug(0, wPlug)

----------------------------------------------------------------------------------------------------------------------------------------------------------

But after is impossible to get value.

I have one solution whis getSetAttrCmds. but it requires to parse string.

there another solution?

I found the solution !

----------------------------------------------------------------------------------------------------------------------------------------------------------

#    For get MFnBlendShape

selectionList = OpenMaya.MSelectionList()

selectionList.add(blendShapeName)

bsObject = OpenMaya.MObject()

selectionList.getDependNode(0, bsObject)

mfn_blendShape = OpenMayaAnim.MFnBlendShapeDeformer()

#    For get weights datas

attributeName = "inputTarget[0].inputTargetGroup[0].inputTargetItem[6000].inputPointsTarget"

selectionList = OpenMaya.MSelectionList()

wPlug = OpenMaya.MPlug()

selectionList.add(mfn_blendShape.name() + "." + attributeName)

selectionList.getPlug(0, wPlug)

wPlugObject = wPlug.asMObject()

pointsArrayData = OpenMaya.MFnPointArrayData()

pointArray = OpenMaya.MPointArray()

pointsArrayData.copyTo(pointArray)
