How do you load a stage without payloads?

[ColinKennedy]

I want to load a stage and have its initial representation to show only bounding boxes (which would be computed using pre-authored extentsHints). To do that, I need to load the stage without payloads to start. How do I do that?

Specifically I would want 2 layers

• a "root" layer that I'm loading. It has a payload to another layer
• a "payloaded" layer, that contains some geometry. e.g. a Sphere Prim to initially bring in as unloaded

I checked around to other posts to see if this was asked before and am trying to piece together the solution. For example

Using that as a basis I tried making a repro and am struggling. If someone can show a working snippet it'd be greatly appreciated

When loading a USD Stage from file, notice the Load Payloads option in the load option. That will load all the payloads. If you don't want that, uncheck that option. After loaded, right click prims in the outliner if you want to load the payloads of just that prim. If you do not click Load Payloads with Descendants, just payloads at that prim level will load and none of the children prim payloads.

Thank you, I figured it was something simple. I enabled echo all commands and found the option that gets called when the checkbox is toggled off. Apparently it's mayaUsd.lib.setLoadRules(proxy_shape_dg_name, False) or something similar. Not at my computer right now but I think that was it. Cheers!
