  1. Hello Dear members of this forum can i please ask for a little guidance. I want to combine three.js and gsap/scrollTrigger. My page structure is simple: two sections both with height: 100vh First section is simple hero baner that is not containing any animation (not relevant for the issue) and the second section is a place when magic should happen. I animating three.js model as soon as the second section hits the viewport and I did it by absolute postioning inside relative parent, creating a timeline with all the changes to model (rotation, scale, lighting, camera movment) and connect it all with scroll trigger (using "pin" propery) and this works like charm. Since I cant use codepen i will paste code here (so sorry) js: const timeline = gsap.timeline({ scrollTrigger: { trigger: ".scene-wrapper", start: "top", scrub: 1, pin: true } }); timeline .to(ambientLight, {intensity: 4, duration: 0.4}, 'scene1') .to(mainLight, {intensity: 5, duration: 0.4}, 'scene1') .to(model.rotation, {y: -Math.PI / 2, duration: 4}, 'scene2') .to(model.position, {x: 0, duration: 3}, 'scene2') .to(camera.position, {y: 0, duration: 3}, 'scene2') .to(camera.position, {z: 4, duration: 2.5}, 'scene3') .to(model.rotation, {z: -0.8, duration: 3}, 'scene3') .to(model.rotation, {y: -2.6, duration: 3}, 'scene3') .to(model.rotation, {z: 0, duration: 3}, 'scene4') .to(model.rotation, {y: -3.1, duration: 3}, 'scene4') .to(camera.position, {y: 0.4, duration: 3}, 'scene4') .to(camera.position, {z: 6, duration: 3}, 'scene4') html: <div class="wrapper"> <div class="section one"> <h1>Funny stuff</h1> </div> <div class="section two scene-wrapper"> <div class="background-container"> <div class="animation-container"></div> </div> <div class="scroll-container"> <section class="scene-1 scene"> <div class="copy-wrapper"> <h2 class="headline">This is 3D Model approach</h2> <p class="subtitle">Lorem ipsum dolor sit amet consectetur adipisicing elit</p> </div> </section> <section class="scene-2 scene"> <div class="content-column"> <div class="copy-wrapper"> <h2 class="headline">Scene 2</h2> <p class="subtitle">Lorem ipsum dolor sit amet consectetur adipisicing elit</p> </div> </div> <div class="content-column"> </div> </section> <section class="scene-3 scene"> <div class="copy-wrapper"> <div class="content-column"> </div> <div class="content-column"> <div class="copy-wrapper"> <h2 class="headline">Scene 3</h2> <p class="subtitle">Lorem ipsum dolor sit amet consectetur adipisicing elit</p> </div> </div> </div> </section> <section class="scene-4 scene"> <div class="copy-wrapper"> <h2 class="headline">Scene 4</h2> <p class="subtitle">Lorem ipsum dolor sit amet consectetur adipisicing elit</p> </div> </section> </div> </div> </div> As you can see inside ".scene-wrapper" i have container for aniamtion AND for 4 sections that i called scenes. My model is pined to a container and stays always on top of the screen (thats desired behaviour) but now i want to hide ans show this 4 texts from the "scens" in particular moments of my aniamtion and I dont know how to approach this.... So question to you dear forum: 1. Should I add animations of each text to the created timeline and create even longer timeline that i have right now or create separate timeline for text ? 2. Do I need second scrollTrigger instance just for texts ? To give you an idea what I want to create please see screenshots NOTE: this is free model downloaded from Sketchfab
