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

scene.set("Physics", "size", 0.15);scene.animate("Physics", "opacity", 0.5, 2);

import { scene } from "motion";scene.set("Physics", "size", 0.15);scene.animate("Physics", "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.
