Deterministic rendering

Is it possible to have deterministic rendering (for the same scene, the pixels are the same) for isaac sim?

Is there any possibility for deterministic rendering for Isaac-sim? I think it’s quite important for the reproducibility of robotics applications.

Hi - Sorry for the delay in the response. Let us know if you still having this issue/question with the latest Isaac Sim 2022.2.1 release.

Hi @nikepupu9 - Can you please explain further about this requirement and use cases?

This is mainly for benchmark evaluations during vision-based AI research.

For example, when we start up with the same scene, the same set of objects, and the same camera locations, the rendered images should be the same.

If there is a way for deterministic rendering, the AI evaluation results will be more consistent with smaller variance.

Maybe we can set up a seed for the ray-tracing sampling process.
