Game Name?
Kirby Air Ride

Game ID?
GKYE01

What's the problem? Describe what went wrong in few words.
Some of the vehicles (stars) in the game render incorrectly, most specifically parts of their diffuse are missing, leaving only a silver-grey specular instead.

What did you expect to happen instead?
Obviously render the diffuse as normal.

What steps will reproduce the problem?
Entering the city trial game, then entering either normal or free-run mode and locating either the jetstar or turbostar (all stars are underground in free-run mode), either will be bugged.

However, if you enter free-run mode and start on either star, and before any start race/demo clips are run (not the actual video clips, but AI race demos) in the menus, both the stars will have the textures loaded correctly and as such will persist through the rest of the time the game is run. But otherwise they will be stuck as grey (yellow-ish for the turbo) for the entire game.

unknown yet if it occurs in the air ride game as both stars must be unlocked before you can use them in said game mode.

fairly obvious that their primary diffuse textures are missing, though the secondary diffuse on the jetstar is still there, of which has no specular or glow anyway (diffuse-only).
