How can I display a usd animation within another scene during a live session?

Hi,

I have a simple usd scene (“myModel.usd”) that is fed via a live session from another tool. As part of that, a prim (a human) is moved around. The prim itself is using another usd file (“walkingHuman.usd”) that includes a walking animation.

Opening the “walkingHuman.usd”, I can easily play the animation:

However, as soon as I try this with “walkingHuman.usd” embedded in “myModel.usd”, it does not work anymore.

I already tried to embed the “walkingHuman.usd” as a proper layer right into the world scene (I think?). But clicking hte “play” button does not make the prim walk anymore

So 2 challenges:

  1. How can I see the animation of an embedded usd file within another usd file
  2. How can I see the animation in a live session where the prim is sometimes moved (would like to see the walking animation) and sometimes not (static animation only pls)

Is this even possible in live sessions?

thx for any pointers

At least the first, should be very possible. Embedding an animated usd file in another master usd file. We do that all the time. Maybe it is something with the actual usd file. Can you attach it here, the walkinghuman.usd. Can you try something very basic and just make an animated cube and call it cube.usd and then see if you embed it in a new usd file, if it animates. Of course it should, but I just want you to test it.

The LIVE sessions are special animals. I will have to look into that separately.

Hi Richard, thx for the response. I attach the walkinghuman.usd, does it work on your end?
