Spatial data management techniques with USD

Development Programming & Scripting Blueprint

Hello!
I am still pretty new to Unreal Engine but I am making my school project " Effective work with spatial data in augmented reality" in it. I am working with USD data and I am finding problems applying some of the spatial data management techniquest such as LOD or World partition.

  1. I am working in USD Stage - how can I make LOD for my imported models in UE? I find LOD in UE quite straight forward in static meshes but for this representation I am just clueless.

  2. I have big USD set of the whole city - problem is that the whole city is one object. Is there a way how can I “split” this object into world partition regions?

I am grateful for anyone who can send me the right way how to deal with is.

I have the same 2nd problem as yours, any solutions?
