Hello @CO_Dae I have to agree with Zed68 here, We really do need a color illumination map if at all possible. Having our buildings have color spot lights during the day will look weird as most building turn them off during the day and at night they come to life. I too have some examples of what I mean. For Instance, It will be impossible to have our tall buildings have lights on them unless we want them looking neon during the day or rainbow during the day which will just look stupid. I really hope you consider this request. As tony pointed out, we think you may have not gone this route because of possible memory increases but I don't think people would be using the full advantage of a color illumination map all the time, and at least give the modders the option to use them if they want.Suggestion would be to make the greyscale illumination always be considered on and anything with the color illumination would only come on during the night and use that color of the illumination map to cast onto the building including gradient lighting such as a dark red to light red to cast a fading red light on the side of the building. Thanks!
