Weapon model transparency

[Topsy]

Hi
Ive made a weapon model and attached bones to it then exported it. I was able to import it into the Editor but it looks like this:

Its the transparency thats the issue. Any reasons why ?

Did you give it a material with opacity yet?
If not then your normals are just flipped
