Hi David,

No, it can be done in Carrara. Where is the blue on the
ice coming from? The surface underneath the cubes?
The walls or the sphere you placed the scene in?
It isn't just from the labels, is it?
If it's not from the labels, select the blue object(s) and
change the color in the Texture Room. The color is correct,
you just need to lower the saturation of it so it's grayer
so the blue on the labels pops out more.

Okay. Reduce the reflectivity a bit then. That will make the
droplets less blue.

The inner edge of the glass isn't showing up. It will increase
rendering time, but you might try reducing the size of the
liquid inside the bottle just a very litttle bit so the light can
bounce against the bottle's inside. You can also make the
bottle just a bit more reflective so it catches the light better.
This will also give you some reflection of the cubes in the
glass. That would be nice. (But all of these things will increase
rendering time. You might not find it worth the effort.)

Yes, it was. I'm a little surprised we don't see any pooling of
light from the caustics. I would expect to see that in curves.
But caustics are always a surprise. :-)

Something you might want to do is save the whole file with
another name (so you don't mess up this one) and then
change the shader for the cubes to a flat (no reflection,
shininess, transparency or highlight) black. Render the file
at the same size as this one. It will really speed up rendering
time because none of the cubes will be visible. You'll end up
with a file that you can bring into Photoshop and drop on
your other rendering (holding down the SHIFT key to center
it) and Viola! You can superimpose the new bottle where
the current one is ... using the black mask to isolate the
cubes from the first rendering.
