Hi there,
Just wanted to let you know - I was in the exact same situation.
What I discovered was:
I set the lightsource in the level to:
Hidden In Game: ON
Visible: ON
And in the sequencer, I chose the “Hidden In Game” parameter on the “Root” of the light, NOT on the lightcomponent. This works in play mode (or when you render out) - not in stop mode.
Hope this helps.
Best, Jesper Colding
