Payloads and unshareable stages?

[pierre-ed]

Hi everyone!

I am having a hard time controlling the load policy of unshearable mayaUsdProxyShape stages.

With shareable stages, setting the .loadPayloads attribute to false before feeding in any .filePath does the trick perfectly.

On the other hand, I cannot manage to declare a proxyshape whose stage would not be shared, and then load its content in a deferred way: it always loads immediately. I tried to uncheck the .shareStage attribute first, let the stage being recreated (with its new sublayering root layer and new session layer), and then explicitly set its loading rules to [ (</>, NoneRule) ] before finally specifying .filePath, but to no avail.

Indeed, a quick look at the code indicates that the stage is reopened while ignoring any load recommendations.

Is there a technical reason behind this specific behavior (the apparent impossibility to open a unshareable stage without its payloads)? Is there any workaround?

As always, thanks for your feedback.
Cheers,
--Pierre
