Hey folk,

        mixer = new THREE.AnimationMixer(model);
            var action = mixer.clipAction(gltf.animations[1]);
            createAnimation(mixer, action, gltf.animations[1]);

function createAnimation(mixer, action, clip) {
    let proxy = {
        get time() {
            return mixer.time;
        set time(value) {
            action.paused = false;
            action.paused = true;

    let scrollingTL = gsap.timeline({
        scrollTrigger: {
            trigger: renderer.domElement,
            start: "top top",
            end: "+=500%",
            pin: true,
