This was the final test done for a recent job. For the job we rendered the bottle on a different angle to match into photography, but I preferred this version for my portfolio. The details of the bottle shape and all the sweat were done with displacement.
The bottle is built in Max, and largely rendered in Mental Ray. The liquid was done in Realflow and rendered with Fryrender 1.9 and composited in Photoshop. All post work also done in Photoshop.
