Hello,
we are working on a TV show and use unreal to light / render shots
we receive USD file for each scene with basic material assignment, so we need to edit / replace those shaders according to our needs.
as assets / animation are evolving, we are not importing the USD and we need to load them as a stage.
In our crash test project, on 5.5.4, we were able to load USD and edit shaders, but we had several other important problems
So we moved to 5.6 that solve everything but material edit / replacement.
everytime we save (both uasset and usd writting) new shading, if we reload the usd, it’s gone and goes back to initial state
we checked the USD files, the material assignment is present.
if we click the reset arrow, the material assigned come back, but never stay
any hint of how we can fix this issue please ?
thank you
