If you can figure out what's wrong, sure - Cream is otherwise very low priority for me =P. It looks like it could be a simple texture issue, but if it's otherwise a mesh problem... I'm not sure I'd bother. From what I can remember, Cream is a horrible monster. The last comparison in this video is very different from the rest. Also re: last note there: materials can have transparency applied directly to them regardless of whether the texture it's using has an alpha channel. If I recall, you fixed them by modifying the textures' alpha channels, right? Honestly, the only reason I haven't used your fixes is because I first want to confirm that it's the texture's fault in the first place; I just haven't taken the time to do it yet. It could be a number of other issues, like differences in rendering behavior between PC and GC (which is most certainly different in fact, it's just not enough to affect everything), material mishaps (which are more frequent than one could probably tell), etc. I'd also almost argue that the basically-completely-transparent water in the GameCube version is "wrong", but I'd certainly agree with you if you were to say that the PC's alternative looks terrible. And a bit of a nitpick, but the transparency isn't missing in that last case you posted, it's just not as aggressively transparent as the GameCube. If you can still see Sonic through it, it's transparent (translucent?). So tl;dr I guess: don't get me wrong, I want to fix that stuff, I just want to make sure this is the best way to do it. That'll help prevent the need to re-do it later.
