This was a fun agency campaign I was brought along to help out with. The designs were created by Peter Tarka, and the initial animations for Earth Month (the first video below) were created before I started. My role was to rig the characters and refine and revise based on client notes.
The second video, I was tasked with putting together the whole thing. Additional rigging was required for the character work, and I particuarly enjoyed working on the family concert at the end.
A mix of tools was used, but primarily C4D and AE with some X-Particles for the sand transformation.
