Difference between render texture Sensor component and Camera Sensor Component?

What is Fast method and What Example situation for use?

 

You should use whichever suits your use case better. If you want to render part of the scene, a CameraSensor is probably better. If you are already rendering to a render texture, use the RenderTextureSensor. If you want to make other visual observations, there's an example in https://github.com/Unity-Technologi...Tests/Editor/Sensor/FloatVisualSensorTests.cs
