trigger: "body",

start: "top top",

markers: true,

scrub: 1,

}

tl.to(mirrors.current.position, {

z: "+= 10",

})

return (

<group name="mirrors" {...props} ref={mirrors}>

<meshLambertMaterial ref={sideMaterial} map={thinFilmFresnelMap} color="#AAAAAA" />

<meshLambertMaterial ref={reflectionMaterial} map={thinFilmFresnelMap} envMap={envMap} color="#FFFFFF" />

{mirrorsData.mirrors.map((mirror, index) => (

<Mirror

key={`mirror-${index}`}

reflectionMaterial={reflectionMaterial.current}

/>

))}

</group>

Hi @V1na. Your demo doesn't seem to be doing anything at all, and there's a LOT of code in there. Can you please provide a much more simplified minimal demo that doesn't use any frameworks? That'll DEFINITELY improve your chances of getting a good answer.

 

Just some colored <div> elements and the GSAP code is best (again, avoid frameworks if possible). See if you can recreate the issue with as few dependancies as possible. If not, incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, then at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

 

Here's a starter CodePen that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo: 

See the Pen aYYOdN by GreenSock (@GreenSock) on CodePen

 

If you're using something like React/Next/Nuxt/Gatsby or some other framework, you may find CodeSandbox easier to use. 

 

Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions.

Haven't tried your code, but it looks like you are missing dependencies in useEffect()

 

Try with useEffect(()=> { ... }, [])

 

Also gsap.registerPlugin(ScrollTrigger) should go outside of your component
