So you are following the tutorial on GitHub and you downloaded Isaac Sim directly? Good.

So I am assuming that you don’t have Launcher installed? Ideally you do not and you are “Launcher free”. The tutorial asks you to add a local Nucleus server. Honestly we no longer recommend this workflow. Let me see if you can download the tutorials directly and get you the download link.

I have downloaded isaac sim 4.2.0 from:
https://docs.isaacsim.omniverse.nvidia.com/latest/installation/download.html#isaac-sim-latest-release

And installed it like this:

mkdir ~/isaacsim
cd ~/Downloads
unzip <"your-downloaded-file.zip"> -d ~/isaacsim
cd ~/isaacsim
./omni.isaac.sim.post.install.run.sh
./isaac-sim.sh

Great. Yes that is the right workflow. Just to be aware, we now have Isaac Sim 4.5 as well. Let me see if I can get you the demo files directly.

Have you tried going back to that same link and downloading the Isaac Sim assets directly from here?

I’m using the Pegasus Simulator (GitHub - PegasusSimulator/PegasusSimulator: A framework built on top of NVIDIA Isaac Sim for simulating drones with PX4 support and much more), which is currently only compatible with 4.2.0

I tried today, but i’m not really sure how to install them, once unzipped?

They should just be normal usd scenes. Just navigate to these folders and open up the USD files.

Perfect, the nvblox is in assets package 2.

I can open the USD file, but it has a default path i looks for stuff:

2025-02-27 08:55:42 [413,295ms] [Error] [omni.hydra] [UsdToMdl] Prim ‘/World/nvblox_sample_scene/carter_nvblox_ros/wheel_left/carter_v2_wheel_left/Looks/fronttire_m/fronttire_m’ parameter ‘diffuse_texture’: References an asset that can not be found: ‘omniverse://isaac-dev.ov.nvidia.com/Isaac/Robots/Carter/Materials/fronttire_m/fronttire_m_basecolor.png’

I have saved the assets at the following path, and this is also where i open the USD from:
~/Desktop/NVIDIA/Assets/Isaac/4.2/Isaac/Robots/Carter/Materials/fronttire_m

Do you have any suggestions for this?

  • Worked anyways

Hmm that is not good. It seems like it is still looking for a texture on our private nvidia server. I will have to address this.
