Hi @RobH_WB, thanks for the explanation. I’ve currently got the same problem. I’m referencing an entire USD scene into my UE level and now want to be able to add materials, lights (and potentially even new geometry) and save all of this as a new USD file - essentially a file referencing the original file and all the changes made to this file.
Going by what you’ve written this is partially doable - though in a clumsy way - and partially impossible. Would you mind elaborating on how to add materials to USD scenes in UE and save those material assignments to the scene?
In the long run, I’d love to be able to layout my scene in in USD inside UE, add all the lighting and material that I need and then either render it inside UE or be able to move back to Houdini or NVIDIA Omniverse.
Thanks for any advice on how to do this.
