I had some very strange lighting going on in my hub, my point light solution was not a good one, so I replaced it with a directional light and a script that turns on and off the directional lights depending on which area the player is in. Kicking myself for not making the hub and level separate now that I’m familiar with casting, but its too late now.
I added a set visibility function to each of the switch branches, turning on the main level light. I then turned this off when the player uses the exit trigger. The lighting is consistent in the hub now, and it really makes the coloured leaves on the tree stand out.
