Doubt in particle animation . please help

i want a particle animation like in this website Website while scrolling.
but now i am getting some weird animation like in this video

this is my code Codesandbox

the following looks very much incorrect…
the traverse method iterates over all of the objects (as a depth first search afaia) in a given scene graph meaning for every mesh object in every scene you’re loading the next model and then again for every mesh object in every following scene so you’re effectively reloading everything recursively to the order of n * model index * model parts… try loading each model individually once and working with individual models…


is it the reason for two models while rotating the points?

It’s almost 100% likely from what I can see…


very helpful
