I've been missing some time to fix all the issues, but i'd say it's "good enough". You might notice a bit of popping in the textures, that's because recording with fraps decreased the framerate to the 30s, which in return made the texturing process "lag" a bit. When it's running at over 100 fps, popping doesn't appear.
In addition in some view angles, the atmosphere is not correctly blended with the ring (a sort of dark halo appears, which makes the ring look ugly). I tried to not show it, but that's something i'll have to fix in the future.
The video is a bit long ( 4 minutes ) and weights 75 MB. Encoded in Divx4 as usual.
