Here are a few product renders
Looks good. How did you model the waterdrops? I assume the bigger drops are supposed to be ice(?) and if so, I would recommend increasing the surface roughness and slightly lowering the index of refraction to 1.3.
Thanks for the comments, appreciate it. The larger droplets are from a 3d model set of splashes and droplets I got from Dosch Design then individually placed. The finer droplets are bump maps placed on a duplicate of the bottle 0.01 percent larger than the original. Applied a liquid material and opacity map, revealing just the drops. As for the comment about the ice chunk I have to disagree. Unless ice chips haven't been submerged in water they will have no roughness and have just about the same refraction as water. I have been shooting beverage products for almost 20 years, both with real ice and studio ice and these look pretty convincing to me.
these are just amazing!!! Specially the last shot.well done
:) great job! The liquid interaction looks great
