asex says I read up the image, the definition of an emission emissive and suggests emissive lights should actually light up yes that's true emissive lights but we're using emissive materials and the way this emissive material works is that when it's rendering when usually when the game is rendering like whatever material in the game it will if it's not an emissive material it will try to calculate how light will hit the material when it's hitting the eye as in the camera but it missed the material it will just look at the material and be like okay what color are you and it just gives you a value I like how bright yeah exactly how bright it is then it just like draws on top yeah so it doesn't actually do any any kind of so emissive lights are actually sorry emissive materials are actually cheaper to render because you don't do any light calculation whatsoever you just don't actually bounce light around the room yeah and they don't affect like any of anything around them
