Niagara simulation Cache for in game cinematic. or vat houidni..?

Hello, I realized that Niagara simulation can be Cache.( particle, fluid, )

in game scene, niagara real time simulation can be heavy. so think about change all as a cache.
not sure is it good choice. cause not sure cache is safe for Ps5, switch platforms…

there is another choice is Vat using houdini. but i don’t know houdini that much. it it will take a lot of time to learn… and vat texture is heavy also…

my personal taste is not learning houdini, focus on unreal niagara,material and cache… but… need opinion from here
