Is there a way to add animations to rigged 3d models in omniverse replicator via python?

Hi @sharanya.pathakota have you tried using omni.replicator.core.modify.animation?

https://docs.omniverse.nvidia.com/py/replicator/1.11.16/source/extensions/omni.replicator.core/docs/API.html#omni.replicator.core.modify.animation

Let me know if this works for you.

I have a usd file that has the skeleton and the animation embedded into it already. However, when I try to use the command you gave above, I am unable to find the correct prim paths. For reference, I am running this headless. Here’s the code I am trying to run:

with rep.new_layer():
        bird_anim = rep.create.from_usd(config['bird_anim'])
        bird_path = rep.get.prim_at_path(config['bird_anim'])

        bird_skeleton = rep.get.skeleton(bird_path)
        new_anim = Sdf.Path() # Not sure what to put here

        with rep.trigger.on_frame():
            with bird_skeleton:
                rep.modify.pose(
                    position=rep.distribution.sequence(circle_positions),
                    scale=0.4
                )
                rep.modify.animation([new_anim])
