1.ReflectionProbe
API: Reflection Probes
to be updated
2.LightProbeGrop：
API: Lighting Probe Set
To place light probes in a scene, you must use a game object that has a Light Probe Group component attached to it. Light Probe Group components can be added from the menu Component > Rendering > Light Probe Group .
A Light Probe Group component can be added to any game object in the scene. However, it is better to create a new empty game object (menu: __GameObject > Create Empty__) and then add the component to this game object, thereby reducing the possibility of accidentally removing the component from the project.
I won’t say too much, I basically know everything by looking at the API
The light is in baked mode. Here is a demonstration of a phenomenon. There is no point in the dark area where the light changes significantly. Then, in the place where there is no light in the middle, the object has no change in light and shade. You need to add points in the transformed "dark area"
