Pixar USD/USDZ import

,

hi guys, is there any planned support from unity for importing USD/USDZ at runtime?
Im writing a mobile AR app that needs to load in large meshes and very quickly “cull” a smaller portion of that mesh for display. This is where USD shines with the “compositing arc” functionality

there is an open source project here but seems unstable on mobile.
wondering if there will be any official support from unity.

For anyone finding this post, an official USD package landed a while ago:

Does not have a runtime api, and does not work with android build settings…

Does this support world partitioning and 64-bit world space coordinates?
