Realizing this commercial using procedural was an opportunity for me to learn a new technique, as it was my first time using Mash.
At ARTFX I had the chance to attend a Houdini procedural workshop, which helped me to pick up Mash quickly.
I first spent several days following tutorials to familiarize myself with Mash by creating different set ups, and using different functions and techniques. I also appreciated the possibilities of using sound to interact with functions – so I decided to lead the commercial with the sound.
I then started to create my own set up in different scenes, experimenting as much as possible. The goal was to realize 8 seconds of abstract dynamic animation, playing with the shape of an owl, while experimenting with sound and strong colour.
The challenge were to find a certain harmony between the different procedural set ups so that they mix well together, to keep the composition of the image interesting, and to play with all the information included in the sound.
In order to optimize my final scene, all the animations were realized in different scenes using the Mash network, then exported to Alembic to be grouped in the same scene. Working this way, I was able to achieve my intended lightning more easily using Arnold’s IPR.
I then created several shading tests while keeping in mind the rendering times.
I then completed the compositing in After Effects to arrive at the final result below.
