Model transparancy problem.

[Shadowth117]

Okay I looked at your pictures. I think I understand the problem now. Try rendering it up once and seeing if that hole is still there. Sometimes stuff like that shows up in the viewports of your program, but doesn't come up once you do a render of it.

If that doesn't work its definitely something in your material's transparency. However I'm pretty sure now that its the issue I described above.
