I was playing around with this last night and it was pretty nifty. Some comments though:
As of the moment the zone is of a Single “hard” Adjustable Directional Key light and a Simple (only position adjustable) Stage (or back) light.
Could we get the zone to support the Three Point Light Setup instead? or basic Imaged based lighting (Similar to Skylight in UE4 based on a texture (when texture is loading, have a grey zone instead), which ever first, it could also helpen to lessen amount of lights overall :). I know HyFy isnt PBR, but better lighting will still could help with looks.
This way the lighting could be made to look at lot more pleasant instead of harsh
Also, currently the transition from zone to no zone and from zone to zone is a bit jarring (especially if you add two zones within each other), can something be done about that, such as fading the lights out/in instead of just cutting them off completely?
