Additional Information
We are generating synthetic data with Isaac Sim. The basic setup is that random objects are scattered in the scene and recently I added scattered grass. The simulation is supper slow. It used to take about a minute for the simulation to start through the extention. since adding the scattered grass, startup is nearly impossible. can take more then 10 minutes just to initialize. and after initialization, a single step will be like 10 seconds each (even if only scattering the camera’s position and nothing else). I am positive that with some basic optimization help I will be able to speed up the simulation. This is my first post of many on the subject of rendering optimization.
