Root upAxis vs sub object upAxis

[TongkuiSu]

Given an URL, we can create an USDStage and we can get the upAxis through USDStage->GetMetadata<pxr::TfToken>(USDTokens::upAxis, &UpAxisValue);, If a scene like Kitchen_set, there are many sub scenes and each .usd has an upAxis, Do we need to parse them for each .usd, or we just need to get it through USDStage ?

No, as a consumer, the stage-level declaration is all you need, as described here: http://graphics.pixar.com/usd/docs/api/group___usd_geom_up_axis__group.html#details

You can also use UsdGeomGetStageUpAxis() to fetch the value , for greater robustness and clarity.

I don't know if it's your use case, but we are decreeing that all "web friendly " usdz files must be Y-up, and the recently released usdchecker utility will validate that in --arKit mode.
