You are mixing two different versions of kit. Isaac Sim 4.5 is still based on Kit 106.5. If you want to share files between Composer and Isaac Sim, using the USD Composer from kit 106.5 Kit App Template. Stay out of kit 107 for now.

Thanks!
I did the warehouse shelter scene again in Kit 106.

It imports just fine to Isaac Sim 4.5 and they now play together.
What is the correct way to solve the scaling issue?

So can I ask why you are using Isaac Sim in addition to Composer? What workflows are you doing that you need to switch to Isaac Sim for ?

We are using both cos we do a large project plan for a customer, and we do:

  • basic velocity keyframe driven simulation of the trucklift taking a pallet and moving it to another part of the shelves in Isaac Sim

  • falling boxes sim + velocity keyframe driven simulation of the trucklift detouring it

  • more professional training of the environment to the automated trucklift, in Isaac Sim

  • Design of the custom built set ( no more NVIDIA warehouse in use ) and lighted and camera animated in Kit 106

  • baking the simulations and bringing them from Isaac Sim to Kit 106 so I can do cinematic renders with path tracing + screen captures of rxt realtime and RTPT rendering engine.
