I've created a small tool that always anyone to tweak the parameters for materials which are coming to Orbliterate! very soon. Head over to the discover page and try it out for yourself
Once there you'll be presented with a gallery of materials that other people have worked on. Click on one of their materials will load the settings they used to create it. You can tweak the colors and sliders to vastly change the appearance of any materials. When you are satisfied with your changes, you can press the save button to capture an image of your work, and other people will be able to see your creation as well.
I hope to see some interesting material settings. Have fun!
