The video shown here is just the raw 3D from the ad.
The final TVC was quite long.
This was done using Maya, mentalray, After Effects & Photoshop.
Whenever there is a relatively simple environment, like a product shot,
I opt for mentalray over other renderers because it has a couple tools that help resolve
glossy rays really well in these situations..
The water droplet trickling down the bottle was run as a particle simulation inside of Maya’s Nucleus engine. Trial and error was a given, but the moment we arrived at a stage where we were happy enough with the particles and their interactions, we cached and converted them to a high resolution mesh.
The droplet animation was also made to dynamically affect the finer condensation in the shaders.
Lighting was done with a couple area lights and reflector boards.
Since the camera is macro on the beer bottle – our final render scene was geometry intense. The condensation and beer bottle needed to be subdivided enough for us to model any imperfections that would help contribute to the realism.
