I will be improving the looks of a few of my creations. hmm, imagine a volcano with the d layer... or a powerplant that looks like the outside of a powerplant. then when you click a button, it would show you how it works... its going to be awesome!
@Everyone I have tried it out, you'll access the decoration layer by pressing b. It will bring up a spectrum with sliders so that you can pick your color, then you draw whatever you wish. press Esc, and you're back to the regular layer, and whatever you drew is now on that layer, and will not be affected by elements.
