bounding box for unloaded payloads?

[sharktacos]

I'm trying to get bounding boxes to display for unloaded payloads using the extents hints attribute, following the example from the USD Cookbook. I'm using the all_in_one.usda file to test this:

#usda 1.0

def Cube "bounding_box_here" (
    kind = "component"
    payload = @something.usda@
)
{
    float3[] extentsHint = [(-1, -1, -1), (1, 2.5, 1)]
}

This works as advertised in USDview. It does not work in Maya, and unloading a payload shows nothing.

What I'm after is the behavior of Houdini which displays bounding boxes for unloaded payloads.

Is this currently possible in Maya?

Not sure vanilla Maya USD but you can definitely do it through Bifrost USD

@sharktacos I think this would be very helpful.

I've tried myself with no luck and have seen others talk about generating a cube using the extents you want to represent the payload and I'd much rather see the behavior we get in USDView and Houdini.

@jcoelho88 Thanks for confirming. Looks like this is a feature request then.
