I'm not really an animator (takes off the disguise), but since I built a Sonic character, I had to try him out in an animation, and a friend suggested turning him into SuperSonic. That was last Sat, on what was going to be a weekend project, but turned into 6 days.
I admit to having to take some artistic licence with his transformation, as I have never seen it on TV or in game, only still pics of him already transformed. So i knew he turned yellow, caught on fire, his hair went super saiyan, and his eyes turned red. http://www.xsibase.com/forum/YaBBImages/smiley.gif
The video is Divx, and it came out a little dark and saturated, not entirely sure how to clean it up better. The one going on my new reel will be full uncompressed, and at its full quality. I may post stills later to show the proper lighting etc... But, over half a gig raw, to 16mbs with audio, im not complaining. http://www.xsibase.com/forum/YaBBImages/smiley.gif
Also, the music, I did find some Sonic the Hedgehog music online, even a song called SuperSonic ( http://www.teamartail.com/music/supersonic/ ). But ultimatly I wanted something a little more epic sounding. Not really in character with Sonic, but it did sound better than Sonic Techno.... http://www.xsibase.com/forum/YaBBImages/smiley.gif
