The starting of Hython takes much longer than the work item cook. Is there a way to set all work items to render on a single instance?

you can potentially set your node to All Frames In One Batch so that it uses the same instance

but maybe better start a PDG Service and make your chosen TOPs use it

I will look into starting a PDG service. The other thing I was experimenting with was wrapping everything as an HDA and using the "all Items in one Batch" batch mode. Although currently it is showing me this error stack on cooking.

[13:09:19.064] Traceback (most recent call last):

flattened_stage = stage.Flatten()
AttributeError: 'NoneType' object has no attribute 'Flatten'

I don't see the normal USD export controls which could be weird. Normally I would make sure my USD is not flattened so file sizes don't get out of control and make sure that there is a default prim set but I don't see any UI for this.

Just tried the PDG services and it worked like a charm. So I think I will just run with that method.
