Well, Chrome Shading is a result of Chrome reflecting the "default" skybox which is ground and sky: So yeah :v:
A few years back I made a logo for use in our sonic project. The logo hasn't been finished in this here video. but it shows how I thought the developers meant the chrome to look like if it were 3D. ( there is a bit of a mistake in the chrome where the ground and sky repeat, I'll fix that later before we release our project. http://www.youtube.com/watch?v=ItM2MSiqGZg&list=UUfDV5xinF2VjLd8LSAAfgCg&index=8&feature=plcp also some more chrome logos from the 80's
thanks man.. the ribbon will blow with the wind in the final. Always liked how the sonic 1 logo was designed, besides CD's its my favorite!
