Deleting variant set doesn't remove from the default selections or prepended variant sets

Josh.n · July 29, 2021, 4:08pm

The docs for PrimSpec mention a mutable .variantSets attribute. Calling del primSpec.variantSets[variantName] removes the variant set definition but there are still entries in the “prepend variantSets” and “variantSets” metadata tags. Not sure if this is an issue on the Nvidia or Pixar side and whether anything can be done about it without manual editing.

Hi Josh,

The command you may be looking for is primSpec.variantSetsNameList

That should allow you to modify that actual variantSets ListEditor

github.com

PixarAnimationStudios/USD/blob/release/pxr/usd/sdf/wrapPrimSpec.cpp#L393-L403


      
          
          
.add_property("variantSetNameList",
              &This::GetVariantSetNameList,
              "A StringListEditor for the names of the variant \n"
              "sets for this prim.\n\n"
              "The list of the names of the variants sets of this prim may be\n"
              "modified with this StringListEditor.\n\n"
              "A StringListEditor may express a list either as an explicit "
              "value or as a set of list editing operations.  See StringListEditor "
              "for more information.\n\n"
              "Although this property is marked as read-only, the returned object "

Hope this helps!
