Unreal 4.24 Universal Scene Description (USD) support

I’m also highly interested in this!

I’d even like to know what the plan is regarding the USDLevelInfo node vs. the UsdStageActor.

A few things I’ve found:

  • You can enable/disable local edits in Unreal by:

    • right-click the *-session.usd layer in the Layers panel, and select “Edit”.

    • make some changes on individual parts of the USD stage.

    • right-click the original root layer .usd file in the Layers panel, and select “Edit”.

    • toggle the eyeball next to the *-session.usd layer to toggle the changes you just made

  • If you right-click the *-session.usd layer, you can add other USD files as sublayers.

    • they’ll show in the UI but I’ve found their actual behaviour is unpredictable

Anyone else tried banging on layering/composition within Unreal? I’d love to be able to export the session layer Unreal is tracking.
