Monster only in darkness???

Yes, but it is possible and i will try it.

But to my knowledge, the game engine does not measure light levels outside of its effect on the players sanity - An exclusion zone would be possible if you could make an invisible box follow the player without colliding with the player under a set of conditions though;
But even then, youd need to be using a lantern (Which might be the point?)

Is the light natural or artificial? (Window light etc, or lantern light?)
Also, in case it isnt clear, im actually trying to think of a way for this to work
