Missing texture paths when running Isaac Sim scene

[jasonchenPJ]

Hi @Abanesjo ,

Thank you for sharing this project.

I encountered an issue when running the scene in Isaac Sim. Several material textures appear to be missing because the USD file seems to reference absolute paths that do not exist on my machine.

The error messages are:

[Error] [omni.hydra] [UsdToMdl] Prim '/World/pool_cut/Looks/Water_Sparkling/Water_Sparkling' parameter 'diffuse_texture': References an asset that can not be found: '/home/john/Documents/isaac_robots/triton_simulation/home/john/Downloads/collected_olympic_pool/SubUSDs/textures/Water_Sparkling.jpg'

It looks like the texture paths may have been exported as absolute paths from the original environment, for example:

/home/john/Documents/isaac_robots/triton_simulation/home/john/Downloads/collected_olympic_pool/SubUSDs/textures/...

Would it be possible to update the USD assets to use relative texture paths instead, or include the required texture files in the repository?

Thanks

Hi, thanks for raising this issue. Indeed it appears the USD had absolute paths instead. I'm attaching the texture files in this comment for the moment.

textures.zip

the high fidelity simulation should work as intended, you can find it under the releasees tab.
