I can’t find a solution. I’m making a space game and at some point i’m only using movable lights in a ambient with all physical simulated bodies. I have a main light that point the player, and the player has some ability to make a bit of light, but still i wish to add a tiny bit of light on everything. So far my only option would be to use emissive color on everything and control global illumination thru a BP. I have been trying to use a sky light, but i can’t make it to work etheir. Currently i’m about to add a phew lights opposed to the main on at a very low intensity, should work a bit but the result is sub optimal.
