I have always love reading what people want from forge, the canvases, the weather, and much more that I've seen discussed. One of the very big things that I don't see talked about very often and I have always thought would add much to the atmosphere and mood; is changing the daytime setting. Yes it's been discussed, but I would like a very complex system that would allow you to radically shape the skybox of your forge map.
Such a system would let you configure how much light is shone on the forge canvas and what natural colors are present not only in the sky above but also onto your map. You would be able to wheel through a 24 hour cycle with each hour having a noticeable, differing affect on your world you are about to create and from there you can make changes from how much light is emitted day or night, clouds present in the sky, and the coloring of the sky. And for those who wish to create truly alien worlds, the options should include the coloring of layers in the sky. Just as sunsets can create a sky that is blue on the bottom, orange above that, and purple resting on top of the orange; you should be able to create a otherworldly sky that has green, followed by blue, and yellow as you continue to rise.
I would love to add a dash of orange and fleeting purple and pink of a late sunset, or the still beauty of a late evening casting a darkness over a quiet cabin in the woods, or the sun partially rising with the bright rays exposing the ruins of a battlefield left from a brutal Covenant assault. Such dimensions such as how the lighting brings in different colors, how much of each shade of the night or day is represented upon your forge map can truly create a world that comes alive with touches that you made. Imagine creating that harsh beating sunlight on a UNSC barracks or orchestrating the simple tones of moonlight shining on a flood-infested metropolitan area.
Thanks for reading and I would love to hear anybody's comments on such a feature.
