Possible workaround to prevent hard crashes. Ignore parent scope, and edit in post.

    def rescope_to_parent(self, parent_scope="/root"):
        # https://github.com/Autodesk/maya-usd/issues/2505 - bug. Otherwise we wouldn't need this
        self._require_file_overwrite = True
        namespace_edit = Sdf.BatchNamespaceEdit()

        # there's no way to avoid this. we have to reparent everything
        for prim in self.usd_stage.TraverseAll():
            parent_path = prim.GetParent().GetPath()
            if str(parent_path) != '/':
                continue
            # /mesh1 -> /root/mesh1
            prim_path = str(prim.GetPath())
            namespace_edit.Add(prim_path, parent_scope + prim_path)

        # https://github.com/PixarAnimationStudios/USD/blob/dc710925675f7f58f7a37f6c18d046a687b09271/pxr/usd/sdf/testenv/testSdfBatchNamespaceEdit.py
        def Has(layer, path):
            return bool(layer.GetObjectAtPath(path))

        root_prim = self.usd_stage.DefinePrim(parent_scope, "Scope")
        layer = self.usd_stage.GetRootLayer()
        has_object = lambda p: Has(layer, p)
        can_edit   = lambda e: True
        results = namespace_edit.Process(has_object, can_edit)
        can_apply = layer.CanApply(namespace_edit)
        log.info(f'Applying Sdf Edits: {can_apply}. {results}')
        layer.Apply(namespace_edit)

MtoA 5.2+ appears to fix this issue.

ansuter commented 2 years ago

Oddly hitting this again. MayaUSD 0.18, mtoa 5.2

I hit the hard crash unless I use the workaround above

santosg87 commented 2 years ago

@santosg87 could you restest this and make sure if its still happening on our side again.

santosg87 commented 1 month ago

closing this one, as i cannot reproduce it anymore. we have made improvements to the plugin export as well. :)
