Hi,  
I have a question regarding scene index. I’m working with the stageSceneIndex from usdImaging and I was wondering why, when we load any stage, the XForm prims do not have any primType. For example with the kitchen set:

But the prim.GetTypeName() gives Xform. And I think I cannot consider that iftype is TfToken(“”) it’s an xform. Any advice?  
Thanks,  
Baptiste

OK I think I get it now. Xform prims are not supposed to produce anything in usdImaging so there is no adapter. But the thing is that I’m trying to work with Scene indexes to avoid the flatenning of xform attributes. Let’s see how it goes…
