I’m having trouble implementing the enhanced THREE.Reflector (allowing for fading reflection) . I have the standard Reflector working, but when I tried to integrate the enhanced Reflector, [JSFiddle - Code Playground](https://jsfiddle.net/3fb6ousc/6/) it wouldn’t run without including: import { Reflector } from ‘three/examples/jsm/objects/Reflector’  
Also I had to amend:  
‘const groundMirror = new THREE.Reflector(’  
to:  
‘const groundMirror = new Reflector(’  
to avoid errors.  
With this it simply uses the standard Reflector & ignores the custom Reflector. Any changes I made to the Shader were ignored.  
If I do get it to run, do you know where to specify the stat & end of the reflection fade?

The modified version of `Reflector` does not work with the latest code base since it has to be a ES6 class. I’ve updated the code so it works with `r137`. Maybe you have more luck with this version: [Edit fiddle - JSFiddle - Code Playground](https://jsfiddle.net/m3tyrLxb/2/)
