just studying some of the techniques outlined in this book, which was kindly recommended by mihai.

it is great!! :)

so here are the first tests with bright-field illumination.
second image is rendered with dispersion and sss for the wine. also the middle glass with the wine has much finer tessellation and there is a very fine normal map on it too. (also some tricking with hiding emitters in refr./refl.)
it is quite funny to see how complex these "small worlds" are.. usually i render buildings :wink:

more to come..C&C much welcome..

thanks justin

here it worked but that must be some log-in / cookie weirdness..
the thing is media fire which i liked pretty much is making it impossible now to embed full size images directly... how stupid.

now it is twice the work.. below are the links to the original 2.5k images.

Try min.us

The renders look great! I think I have to buy the last edition of that book, I only have the first :P
I'd just make the wine more transparent...

I just studied the same book, great resource. Concerning the lightning of glass there are different approches described in the book. What kind of lightning did you use for the background light ? An opaque background illuminated by sport etc. or an direct light in the background ? What kind of material did you use for the ground plane of the glasses ? An tranparent , glass like or something different ?
Here is my simple scene i play around with ...https://dl.dropbox.com/u/15698846/bott2 ... e_0001.mxs
