I can read other prim attributes, but if an ActionGraph writes to its own attributes, those updates won’t be reflected in a way that is readable by other ActionGraphs.
I’ve tried various combinations of readUSD/writeUSD. I’ve tried using the variables. I’ve tried reloading the stage. I’ve tried chaining different sequences of Custom Events.
Nothing works. I gave up and am passing data between graphs using Custom Events (which has its own separate problems due to bugs in the Bundle nodes).
I get that the Fabric Storage and the USD storage are separate, but for the life of me I can’t get data to pass between graphs using writes.
