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

scene.set("Sound", "volume", 1);scene.animate("Sound", "opacity", 0.5, 2);

import { scene } from "motion";scene.set("Sound", "volume", 1);scene.animate("Sound", "opacity", 0.5, 2);

The example scenes with a Sound layer in them. Each picture is the whole scene, not the layer alone: open one to see what the layer does in it.

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.
