Isaac Sim seems like it largely focuses on smaller sized scenes for indoor robotics. My lab wishes to use Isaac Sim for outdoor field robotics with large maps. I've noticed a great deal of lag when importing outdoor scenes from Unreal Engine, especially scenes with foliage and fauna. I suppose this discrepancy is because of Unreal Engine's nanite foliage optimizations. Could there be considerations to make Isaac Sim work with fast performance for large scale scenes that simulate the outdoors and outdoor foliage?
