SA-55, Orbot, and Cubot found a new home here after RTB exploded.

Fixed Shadow's eyes

Fixed Shadow's alternate textures.

Fixed some missing textures.

Shadow - Added Chaos Hero/Dark and Super Shadow skins, courtesy of Hyperchaotix
Eggman - Added a lot more flexes.
Classic Eggman/Robotnik - Added a lot more flexes.
(Classic) Metal Sonic - Added eyeposing (as separate models).
Death Egg - Actual-sized model added, original is now DeathEgg_Skybox. You know, since you were supposed to put it in the skybox.
Death Egg Robot - Fixed broken rigging in certain spots, updated the smoothing and added glowy green lights and eyes as alternate skins.

Added Eggman and Classic Eggman/Robotnik's glasses and moustaches as separate props, just because.
Added Rouge's heart bomb.
Added Omega and Perfect Chaos, courtesy of Chaofanatic.

Fixed the phong exponent texture (oops!).
Fixed the eye refract on everyone (except for Eggman/Robotnik, obviously).
Fixed the oversized Shadow's "HideEyelids" flex morphing his mouth as well.
Fixed Eggman, Classic Eggman/Robotnik and Egg Robo's fingerposing even more.
Toned down the environment maps on Eggman, Classic Eggman/Robotnik and Metal Sonic.

Migrated the Egg Dragoon, Egg Pawn and Egg-Robo to the new "Badnik" pack.

Added Rouge the Bat.

Added a larger Metal Sonic and Shadow due to popular request. Please note these are not the proper size of the models (they're oversized like the old Unleashed ports). If you want to stay official, continue using the regular models.

Added Shadow, fixed Egg-Pawn's fingers.

Added Egg Dragoon.
