Is there anything like a light blocking volume that you could set up a point light with a large radius and put a volume in the center of it that would block out the light? or another use could be blocking off a room so light doesn’t bleed through if you turn off cast shadows on the light.
If you mean the radius then that is circler and its impossible to fully illuminate one room and not the one next to it. If it was a square radius instead of circler then that would be possible.
