The final shot of the Dream of Dolls Dancing sequence takes place under water. The mermaid is floating and the One is sinking. I shot each character separately over a greenscreen, created bubbles in Cinema 4D, and assembled everything in After Effects.
Since I am only doing one shot with a downshooter, I put together a temporary set up with my existing materials instead of constructing something more permanent.
Once the two characters were animated I brought them together in my After Effects composition and rendered the partially completed piece as a JPG still image sequence. To create the bubble effect in Cinema 4D, I imported the image sequence for use as a backdrop and constructed an invisible model of the sinking creature to displace the bubbles made by the particle emitter. Then I rendered the C4D bubbles as a transparent PNG sequence and put it together with the other elements in After Effects. A still image of the final result is at the top of this post.
The next step for this project within a project is to work on the sound design……
