Detailed Description

Take a long time (around 20 mins) to open an USD file in Isaac Sim ver 4.2.0

Steps to Reproduce

  1. Open an example in Window → Simulation → Demo Scenes → Rigid Bodies → Center of mass
  2. Add a sphere with Mesh type
  3. Save as another .usd file
  4. Open the USD file from step 3 → this took around 20 mins…

Additional Information

What I’ve Tried

  1. Re-install Isaac Sim/ Reboot PC
  2. Clear catch
  3. Load other USD file with few object (still take a long time around 10 mins…)

I could not replicate the issue on my end; it took about four seconds. Additionally, I noticed the warning, so I do not believe it is related to this.

Could you share your .usd file?

3

I can’t upload .usd file for the system restriction. So I share the link.

Here are two of .usd files. The snow man one is from example and add other objects, and the second one is created by myself. Both of them need to be loaded for around 10-20 mins.

Created by myself

Both items open in under 3 seconds.
