Darksun, please read the stickies! In there there is everything about transparency and .wrl editing. Anyway, here's the .wrl link out of the sticky....
http://web3d.vapourtech.com/tutorials/vrml97/en/tut11.html
EDIT: And as I see you not knowing about .wrl, the kratisto decompiler, transparency... I would suggest to read as many tutorials as possible. Even if you think "I don't need this tut" just read it! In many tuts there are 80% unneccessary and 20% useful stuff mixed together. By reading even non-subject tuts you will learn more and more without noticing, but later some problems just won't exist, because you already know the solution. Just a hint...
