Adding Animation To Characters for SDG

[MekkerMax]

Hi using isaacsim 5.1 i want to create a SDG script that spawns multiple characters from the issacsim people assets
(https://omniverse-content-production.s3-us-west-2.amazonaws.com/Assets/Isaac/5.1/Isaac/People/) and adding some animations
(https://omniverse-content-production.s3-us-west-2.amazonaws.com/Assets/Isaac/5.1/Isaac/People/Animations)
This has not worked, and im not able to get the animations to work when manually placing the models and animations.

CLASS PeopleGenerator
FUNCTION CreatePool(count):
FOR i in 0 to count:
1. CREATE Xform prim at path "/World/PeoplePool/Person_{i}"
2. ADD REFERENCE to random Character USD (from list)
3. UPDATE Simulation (Force USD stage to load hierarchy)
4. DEFINE Animation Prim at "{person_path}/Animation"
5. ADD REFERENCE to Animation Clip USD (e.g., walk_loop.skelanim)
6. SEARCH recursively under Person Prim:
- Traverse all children
- IF child type is UsdSkel.Skeleton:
STORE as skeleton_prim
BREAK
7. BIND Animation:
IF skeleton_prim found:
- Apply UsdSkelBindingAPI to skeleton_prim
- Set AnimationSource to Animation Prim
ELSE:
- Log Error: Skeleton not found
8. APPLY Semantics ("person")
RETURN list of created person prims

i could play animations that were attached to biped_setup.usd but none of the other characters

Thank you for posting this. If the goal is “spawn multiple animated people for SDG in Isaac Sim 5.1”, the supported way is:

• Use the Actor / IRA (Isaac Replicator Agent) system and Actor Control to spawn and control people.
• These actors are already wired internally to the appropriate skeletons, animation graphs, and controllers; you do not manually bind .skelanim to skeletons in your own code.

Implication:
If you just want randomized walking / idle / simple behaviors for synthetic data, don’t re‑invent the animation binding; use the Actor/IRA “people” presets and their documented APIs.

Closing for now. Please re-open / open a new ticket if you still need any support.
