Cheers for your thoughts,

Matt: The reflectivity was probabaly set too hich which could be why the base looks sort of metallic, the shader that I made is completely transparent so that's all it could be really.

Tom: Thanks, it really was a rush job though just to get my head away from my previous project. I think that I spent a total of half an hour on it, mainly messing around with the lighting.

Andy: You're right, there is no direct light source in the render, I'll try one out next time.

I'll make another scene later (once the kids are in bed!) as I didn't bother saving this one after I had rendered it, I don't think that I should have any bother reproducing it, I'll have a couple more shots at making it more real looking.

Thanks again,

Mat.

edit,

ZoharO, you posted as I was replying...

the base of the glass looks that way because of the refractions, I'll try to clear that up when I make the scene again.
