Hey Guys,
I'm pretty sure I'm either adding this attribute wrong, or missing something
else. I keep getting an Error when trying to add a kNurbsSurface attribute to a
node using MFnTypedAttribute (maybe that's not the correct Fn to use?).
The error pops up when the attribute editor is open. The error I get is:
Cannot use data of type no type in a scalar operation.
Start of trace: (file: C:/Program
Files/Autodesk/mentalrayForMaya2015/scripts/AETemplates/AEmentalrayNewMessage.mel,
line 25).
AEmentalrayReplaceMessage (command window: line 1).
AEbuildControls (file: C:/Program
Files/Autodesk/Maya2015/scripts/others/updateAE.mel, line 530).
updateAE (file: C:/Program
Files/Autodesk/Maya2015/scripts/others/showEditor.mel, line 4402).
autoUpdateAttrEd (command window: line 1).
which doesn't mean a whole lot to me unfortunately. The code looks like this:
fnTypeAttr = om.MFnTypedAttribute()
op.inSurface = fnTypeAttr.create("inSurface", "inSurf",
om.MFnData.kNurbsSurface )
fnTypeAttr.setReadable(1)
fnTypeAttr.setWritable(1)
fnTypeAttr.setStorable(0)
fnTypeAttr.setKeyable(0)
op.addAttribute(op.inSurface)
So how best to add a "inSurface" attribute, if I'm doing it wrong, or how do I
fix this error if I am adding the attribute correctly?
Thanks!
Kev
