Well ive sorted the problem now, thanks for the advice guys, i have a new problem however and im sure the answer is very simple.
I am trying to fill a face with glass but only one of the sides is coming up translucent, the otherside is not see through, this creates problems with the rendering.....example
translucent side:
non-translucent side:
Anyone know how to correct this? ie...make both sides see through
