Multiple environments in the same scene slow down the FPS #20

Hi, I am using this repo for my RL training using mlagent. As the doc of mlagent recommends for parallelization, you can simply copy your environment in one scene multiple times and get a training speedup.

When I used grid-sensor and did this simple copy, I got a bad performance, e.g., the agent just did not move and the FPS is very low. I am wondering if this is a problem because you use tag to identify the Detectable GameObject and if you have multiple environments containing the same tag, then there's too much to process.

Thx.

Hi, the tagging shouldn't be an issue with multiple environments. If you look at the example projects, https://github.com/mbaske/grid-sensor/tree/master/Assets/Examples - in Food Collector for example, you can easily stack a couple of platforms on top of each other without affecting performance too much. Each sensor should only process the Detectable GameObjects inside its respective detection area.
