How to make a custom object "chrome" or Transparent?!

[Amnesiaplayer]

another question, Can you make something in maya, and keep doing the "assign new material" etc, and then just export all, and have the "object" you made with all the textures etc in amnesia?! I did this, I made a kinda turtle thing, but in the model view, and editor, it didn't had textures. and not all the parts. only the shield..
Or is it because you have to wait?! everytime I do the "Export all" thing it says like :
Time to export file *blabla* : 183
Do I have to wait 183 seconds until it is finished or what?! Because I just see the Turle.dae and Just use it but that doesn't wait, so do you need to wait etc, or do you need to include ALL the textures you used, in jpg files WITH the .dae file... (Like having 10 images in the file "turtle" including the Turtle.dae and open the model editor etc etc)

I click on "export all" and export it. (Triangulate is on, Lights etc off. I did everything)
