Can somebody help me?

I'm trying to make a stage called "Comet Observatory", but when I import the model into Brawlbox, there are textures that either turn completely black or become black and white versions of themselves. I'm trying to make the stage go over Rainbow Cruise. Please help. Here's the model: http://www.mediafire.com/file/smq4b4n1m9g0e1j/Comet+Observatory.zip
