To visualize a trajectory of a mobile robot in Mujoco, I added 10000 small spheres (using 'site' in MJCF ) in advance and modified the positions of the sites online. Actually, that worked well. But, my problem is, I found that only 950 spheres were rendered in simulation, and I could not visualize the whole trajectory in an episode. Can I change the maximum number of sites? How can I address it? Thanks very much.
