Animating a Suit-Up Sequence

heyo friends this is kinda important, how would I animate a moon knight style suit up sequence or like nanotech style where the suit spawns out of nowhere without just tweeting the transparency? I want it to be something like this but the suit appearing starts at the legs and slowly moves up to the head

it doesn’t have to be that complicated, just that the bottom part of the legs has the suit texture while everything else is the normal texture, then the part that has the suit slowly moves up while the normal part gets covered by the suit

particleemitters and such should work well enough

How do you mean? I want to dynamically change part of the texture over time
