Isaac sim simulating subsets of the environments

In the manager-based environment (or whatever environment class), we simulate the simulation by using “self.sim.step()”. This causes all environments to be activated and move simultaneously.

However, I want to activate only a subset of the environments. For example, out of 4096 environments, I only want to simulate environments with IDs 0 to 100, while the others remain inactive.

Is there any way to achieve this in Isaac Sim?

It’s not possible to step physics for only some environments, but there are APIs in physics that let you disable individual rigid bodies or mark ones as kinematics.
