Item Mall Wear Item(Show Animation)

hello i have an idea but i think it is necessary to go deep to do it, maybe it needs source code, my aim is to make animations to the characters for customization of these characters, but it would be good for the player to see it before buying it, so I'm thinking of putting a button like show animation here, but first I would like to know how the wear item button works, so is this sro_client.exe linked in gameserver.exe?

This is completely client side feature.

Even if they know they won't help.

it can be done by reversing that function
