Help with animation of modifiers

I know that advanced developers make VFX in a blender and then export it to roblox studio. I would like to understand how they do this. I was animating modifiers in blender, but I was having problems exporting. Please help me understand how “advanced” developers do this. Do I need any scripting skills for this?

P.S.: I’ve been puzzling over this for a month now.

You can’t export dynamic animations (modifier-based animations) to the studio. You can only use bones to animate and export to studio.
