    Hi ,

    I use (during training )SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex); to reload the current scene , the moment above is line is hit I am unable to view Ray Perception Sensor 's rays in scene view.

    until the SceneManager is not triggered , Ray Perception Sensor rays are visible in scene view during training .

    Is this bug ? or am I missing anything ?

    no errors or warnings just raycast wont work.

    Thanks

    We'll flag this for the team to have a look. Which version of C# and Python are you using?

    HI @hammer_head,
    Which version of ML-Agents are you using? There was a fix in the latest release for scene loading issues. Could you try that out and let us know if you're still seeing the issue?

    Hi ,

    I am using Latest_release , I still see the issue . To reproduce the issue download Unity flappybird , attach a ray sensor to Bird , you will see sensor will do fine till bird dies , once the bird dies the Scene is recreated with SceneManager and this in turn vanishes sensor from scene view and we can no longer see sensor rays.

    Version information:
    ml-agents: 0.16.0,
    ml-agents-envs: 0.16.0,
    Communicator API: 1.0.0,
    TensorFlow: 2.2.0-rc3


    Thanks
