In my three.js project, i have a static scene, that I want to add lighting and shadow to. Since its static, I dont need to re-calculate lights and shadow each frame. When it comes to shadows, I can simply set

        this._renderer.shadowMap.autoUpdate = false;
        this._renderer.shadowMap.needsUpdate = false;

after the first render call. Is there something similar for lighting ? I know i can bake lights in blender, but I would prefer to do it within three.js.

I tried researching, but couldnt find anyhing so far.
