Metal Sonic Lost World (2016 Preview Video 5)

Now that E3 is over, here's a new preview video for my Metal Sonic Lost World mod's upcoming update.
In this video, I showcase some more "fixed" animations (mainly the ice skating ones.) More importantly, I showcase some major changes to Metal Sonic's model(s).
First, I replaced Metal Sonic's eye meshes (and eye materials) with Sonic's original ones, which FINALLY makes the model support Sonic's pre-existing eye animations.
I did some tricks with transparent textures and an extra mesh in order to make the eyes look almost no different than they did in the previous few videos (well, other than the addition of a reflection map.)
Second, I added some purple fire effects for the engine in Metal Sonic's back (mainly for use in running animations.) These effects are part of Metal Sonic's model (rather than separate effect models,) and are hidden inside Metal Sonic's torso while not in use.
I'm still working on adding them into any appropriate animations that I'd previously fixed (the fire effects only show up during the main "running" animations at the moment.)
Finally, I gave Metal Sonic a clean circular shadow by replacing Sonic's shadow-model with the one used by the playable snowball.
I had to do some scaling manipulation to the skeleton in order to make the shadow appear at a normal size, since the Snowball's Shadow is normally way too big. Thankfully, I only needed to alter an otherwise unused part of the skeleton for this.
I also made a few other minor changes (such as the addition of some light-blue coloring on the fingers, a slightly better mesh for the sphere-cap on the back of Metal Sonic's head, etc.)
