Can't put Unity animation on 3DS max

hello I need help importing stuff from 3ds max to Unity, I’m trying to put this animation onto 3ds max however it won’t animated such as the particle array won’t animated or the small vertices from the main model could anyone help

So, to be clear: you created a model in 3DS Max, and you’re trying to export it to Unity. Your model has particle system and vertex animations and these won’t transfer from 3DS Max to Unity.

This behaviour is entirely expected. Particle systems, vertex animations, materials, and many other things that you can create in 3DS Max won’t transfer to Unity. You’ll have to create those things within Unity. The only animations that will transfer are skinned mesh animations.
