Any USD experts here?
Does anyone know if it’s possible to switch USD variants via sequencer?
I’ve imported a simple geometry variant USD file and can switch between my variants in the USD Stage editor.(attached)
I’ve also created an empty sequence and dragged my USD Stage Actor to it.
But there doesn’t seem to be any exposed methods or parameters for switching variants.
Short answer is no.
Long answer is you can add events to your level sequence that would call blueprint functions. In those blueprint function you can then call a python script that will go and set variants on your USD cache.
But stage actor access, through python API, works in editor only so I do not think it is of interest for you.
