Whenever I activate a SOP Import node in this scene I get this error:
Error while authoring a USD Preview Surface shader

On the light node I am getting this failure:

The funny thing is, I cannot find the attribute
verticalAperatureOffsetConverted
on the camera node at all to fix that one.Then finally on the Karma node I am getting this error, which I cannot figure out why the node is throwing one:
Invalid source /stage/karma1/karmarenderproperties/renderproduct

The artist has shown that the shot renders on his box, but I am getting these massive, low level errors which are preventing me from fully debugging the shot properly. Any ideas. I have tried rebuilding the nodes in scene and in a clean scene. The camera still throws the python error and the karma issue still happens with a clean scene. I did install a copy of the Pixar Python library for some other testing on a different project, could that have broken things?
