How do I make script that equips a certain morph based on a group rank?

Welp you can use the :IsInGroup() function to check if the player is in a group, if the player is, then check to see what rank the player is by using :GetRankInGroup() function and equip the morph accordingly.

Script will look like this:

local Player -- Please find a way to get the player
if Player:IsInGroup(--[[Group Id]]) then -- Check if player is in group.
	if Player:GetRankInGroup(--[[Group Id]]) >= (--[[Rank]]) then -- Check to see if player have a certain rank and if the player do,
		-- Equip the morph
	end
end
