No worries with WebGL1 for now, lets try only those with webgl2:
Case1: https://playground.babylonjs.com/#2FDQT5#1105
Case2: https://playground.babylonjs.com/#2FDQT5#1106
Case3: https://playground.babylonjs.com/#2FDQT5#1107
Case4: https://playground.babylonjs.com/#2FDQT5#1108
This probably I hope the one before last to identify the culprit 
Case 1 - not working
Case 2 - working
Case 3 - working
Case 4 - working
I hope we getting closer and reach and Island
Yup, it looks like “const in” is not supported on your device (despite being fully specified and working everywhere else…)
Let s now check if “out” is working (only webgl 2 as well):

And if “in” alone is working to isolate const:

Then I ll try to automate in the full PBR the solutions to see if that works.
