USD Import: purpose and instance proxy options #16

Open kowalskima opened 3 years ago

kowalskima commented 3 years ago

It would be helpful to support the following USD import stage traversal options:

See the attached puposeTest.zip for an example USDA containing primitives with assigned purpose. See the Kitchen_set_instanced.usd in Pixar's Kitchen Set for an example with instanceable prims.

I've already implemented these changes in a local branch, including a fix to a small memory leak in the stage traversal code where a reader is instantiated for the pseudo root but is never used or deleted.

I'm attaching a screenshot of the new options in the USD Import dialog.
