I am leaning toward adjusting the amount of gray I added to the envirosphere. That was how I got it to darken. So that's how I will lighten it.

Thanks all.

@RedPhantom: yeah, Blender is looking better and better everyday. I downloaded a couple tutorials from YouTube that showed how to create a building and then destroy it, like what they did in the first Avengers and in Man of Steel, so that got my juices flowing. The same guy also did one on creating lava and an erupting volcano, and Darth Vader's helmet. Blender is looking real good right now. Once I go back to work and I have stretches of time with no internet, I'll get back into it (I've said that before, so we'll see if my lazy butt actually does it).

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
