env_spacing = 0 leads to an error

[dhruvkm2402]

Hello,
For using Omniverse ISAAC Gym for parallel RL I want to spawn all the robots at one location, I try to set env_Spacing=0 but it leads to an error. How do I change that? If I do env_Spacing = 0.5 as an example, it works.

Hi @dhruvkm2402

The problem could be in the way Omniverse Isaac Gym filters collisions between environments so that they are ignored.
The following post may provide some guidance on the issue: isaac-sim/OmniIsaacGymEnvs#3

Hi Toni,
yes, the error is related to gpu buffers. I increased the size of each, referred to the anymal example and it worked.
