That is not really a scripting question? Directly copying them is kinda meh too… How about emulating something similar?
I would just use the wide array of attachments and constraints we get baked in to roblox!
Tie some parts into a sort of “Sheet” and give each one of them a downward velocity with very little force and speed.
I have something similar with that also use beams heavily. So it even leaves an aura! Its just a built model however. No scripts (other than cheating at alignment lol)
Animations would be best to learn however. A lot of fun with bones lol
