Isaac rendering of ray tracing / path tracing

[auee028]

Reading the documentation of robosuite/docs/modules/renderers.md:

Here is an example command to render an video of a demonstration using ray tracing with the RGB and normal modality.

$ python robosuite/scripts/render_dataset_with_omniverse.py --dataset /home/abhishek/Documents/research/rpl/robosuite/robosuite/models/assets/demonstrations_private/1734107564_9898326/demo.hdf5 --ds_format robosuite --episode 1 --camera agentview frontview --width 1920 --height 1080 --renderer RayTracedLighting --save_video --hide_sites --rgb --normals

I met some problems as follwoing:
1. Which versions of Isaac Sim and Isaac Lab do I need to install?
The most recent version currently is Isaac Sim 4.5.0 and the code provided by robosuite doesn't seem to be based on the most recent versions.
2. Is the .hdf5 file not available?
While the --dataset argument is necessary to be given to run the example command, but I cannot find any of .hdf5 files provided by robosuite. Should I make a .hdf5 file by myself? If so, how can I do that?

Additionally, the documentation of robosuite/docs/algorithms/demonstrations.md says:

We have included some sample demonstrations for each task at models/assets/demonstrations.

but I cannot find the directory or any provided .hdf5 files. Where are the sample demonstrations available?
