Hello,
In the PBR skin tint demo there is an error with metersPerUnit which makes the inspector nodes invisible.
If I deactivate line 42. the problem is corrected :
scene.enablePrePassRenderer().subSurfaceConfiguration.metersPerUnit = 0.07;
Or fix by :
scene.enablePrePassRenderer().metersPerUnit = 0.07;
subSurfaceConfiguration not found
