The fire in the Vote scene was surprisingly easy to animate. I thought this would take several days, but I had it finished before lunch. In the previous version of the shot I simply added a black and white depth map to the shot and that offered the illusion of depth.
My approach this time was to only apply a depth map the the people standing in the forest. They were then rendered and imported into After Effects with a green screen background. The forest, I broke apart into multiple layers. Furthest from the camera was the background and then three different layers of trees. There are distant trees, mid ground trees and then two foreground trees. There are also two painted layers of smoke.
All these layers were stacked in 3D space like dominos with the background furthest from the camera. The amount of movement in the depth map of the people gave me a hint on how much to move the camera. I just needed to keep everyone’s feet in the same place on the ground. That subtle camera move from left to right, offered the needed parallax effect.
For the fire I imported the painting I had done of the flames. I found a free displacement and fractal noise fire effect online from RocketStock, and imported it into my After Effects presets. I simply applied that fractal noise to my flames and with a series of adjustments had some convincing flames.
I went back into several previous scenes and used this new effect multiple times. It is most convincing with small flames. I also stated using it behind other animations I had done to add more break away flames at the tops of the fires. Most fires now consist of multiple animation layers to add chaos. None of the fires are perfect but this is the style I am looking for.
The painted smoke was animated using pins and then I created a fractal noise smoke effects which I layered on top. The opacity of the added smoke was dialed way down. This shot which passed as “good enough” now feels exceptional. With all these effects shots being refined that is how I am feeling about the film as a whole.
