Node-based edit workflow confusion about blenderusdhydraaddon HOT 1 OPEN

Hi.

Thank you for your nice words.

You allowed to modify imported USD scene via USD nodes (e.g. transform, instancing, filter etc.)

Yes, all USD nodes recomputes if there is changes in scene happen, so they return up to date USD stage.

1. What kind of unsaved changes? USD File node recomputes (reads pointed file) on changing input, output or its modifiers (e.g. import animation).
2. Write USD File node also recomputes when you modify node tree (add new nodes, modify existing).
3. It doesn't sound like a valid workflow - you can't be sure in what order nodes are updated.
4. In any case to be sure that you export up to date USD stage, better to just reconnect Write USD File after all.
5. Seems like you have Blender Data node with checked "import animation", in this case you have to either uncheck it or click Update animation button to make this node recompute changes. It works this way due to infinity loop on animation update. I approve that you able to modify scene and node tree will be recomputed with new data immediately.
