help with skin

[groovy]

ok i am in need of some assistance from someone that knows what they are doing when making bike skins. i have watched several youtube videos and have tried everything I can think of to fix this. I made a bike skin with text and different colored plastics and everything, but every time I put it in the game it appears like it is in the picture below. It is like there is something blocking the color from showing in the final thing. but in the proof it looks perfect. Cheers!
