Unreal Engine 5 .USD Level Export

Hello, I am new to Unreal Engine 5, I am a VFX artist and I would like to know the proper way to export .USD levels into a DCC like Maya.

When I export it in “Asset actions” > “Export” and bake materials, then I try to render in Arnold, the textures seem to be off…, is there a way to export as usdz in UE5 so I can rewire all the textures in Arnold ? if so, how ?

I also would like to know why “Grass Type” doesn’t export properly, basically I would like to export all my foliage as well.

Thank you in advance for your time and help.
