Hello, i got a problem :/

 From:  klego
So, I downloaded the trial version and i have to say i really like this software.

Anyway, for some reason when i save my object it looks alright. When i upload it to p3d.in it looks like this: http://p3d.in/VRraB

Any idea why it does this?

Quick answers would be awesome, 27 days left! :D
