From a script

Every setting above can be changed by the scene's logic, by its key. Say the layer is called Flock:

scene.set("Flock", "size", 3);scene.animate("Flock", "opacity", 0.5, 2);

import { scene } from "motion";scene.set("Flock", "size", 3);scene.animate("Flock", "opacity", 0.5, 2);

What every layer has

Besides its own settings, every layer has its opacity, blend, placement, quick effects and an effects stack. They're listed once, on the layers page.
