Question Can I have multiple Vector Sensors?

    I want to use multiple Vector Sensors for my observations, due to different requirements in stacking and just better separation overall. However, I'm having some trouble doing so.

    First, I added an additional VectorSensorComponent to my agent in the editor. Then, in my Agent script, I run GetComponent<VectorSensorComponent>() and set it to `_vectorSensorComponent` to get the vector sensor component which works well. Then, whenever I receive some game related events that require updating the vector sensor, I try doing `_vectorSensorComponent.GetSensor().AddObservation(someObservation)`. All of this code runs fine; however, in the logs I notice that MLAgents is complaining that there were 0 observations recorded for this sensor even though I am sure the code to add observations is getting called (verified using Debug.Log).

    I was wondering if having multiple VectorSensors is supported, and if so, how to go about doing this.

    I'm having the same issue. Looks like VectorSensor clears all observations in Update before actually using them
