Hey kkim and welcome to the GreenSock forums.   ScrollTrigger works great with Pixi (and all other Canvas and WebGL libraries)! Most likely what you want to do is make some fake content/height so that the page scrolls. For example you could do body { height: 300vh; }. This will make your webpage scroll. Once it scrolls, ScrollTrigger can use the scroll position to do what you need it to do  To keep the Pixi canvas in place, give it position: fixed and make sure its width and height tak
