Way to customize how reflection probes are baked in Unity
In short, you place a Reflector Probe in your scene instead of Reflection Probe. It wraps on top of Unity's probes and offer all the same features.
Except it also offer you a property to hook a camera of your choice. This allows you to plug in a camera with post effect on it, to give your reflection special looks. For example, a reflection with bloom in it gives a nice effect on brushed metal where environment should look sharp, but light source should be blurry.
Another advantage of using a custom camera is the ability to hook custom sky that another camera is seeing.
Under the hood, it also offer better frame splits when updating. Unity "frame splitting" is 1 frame per face, while here it goes up to 4 frames per face (some blit done once at a time)
Tested on 2017.3.1, but should work on pretty much any version with Reflection Probes.
