Known Issue: Assets not downloading

There is a known issue that downloading assets on the first run of Isaac Sim gets stuck at 0%.

This issue will be fixed in Cache 2021.2.2 or later.

A workaround is to disable Cache 2021.2.1:

  1. Go to http://localhost:3080/
  2. Click the Stop button for Cache v.2.4.8-793.
  3. Next, run Isaac Sim and download the asset.
  4. Once the download is done, you can start Cache at http://localhost:3080/

Another workaround while keeping the Cache enabled is to add the Isaac mount on Nucleus.
See 6. Setup FAQ — Omniverse Robotics documentation.

For me, it’s still stuck. Is the double slash after amazonaws.com a problem?

2021-11-27 18:29:28 [17,336ms] [Info] [omni.isaac.core.utils.nucleus] Downloading asset 1 of 7181 from https://ov-isaac.s3.us-west-1.amazonaws.com//Environments/Grid/default_environment.usd to omniverse://localhost/Isaac/Environments/Grid/default_environment.usd

It is fine. What output do you get when you enter the URL on the browser?

Cache 2021.2.2 is available on the Omniverse Launcher. Please update Cache for the fix.
