Help with making looping gif pngs?

[Idia]

I wanna swap some looping gif pngs on two outfits I'm working on.
However, I'm not quite sure how to go about making one! Does anyone know any tools or tutorials to make one?

From what I know.. EXTENSION seems to use something called MotionElements but it looks paid/subscription based? AND I'm not quite sure how to use it.

Anyways I appreciate any help given! Thank you in advance!

You can use poiyomi flip book, drag and drop your gif into texture array and scale it however you want it. (make sure you set your gif to transparent in unity)
