Hello, been looking into how to do a lens of truth effect where you cant see certain sprites unless you have a an item, made a post about it here

Cant seem to figure it out for 2d as almost everything relating to this is for 3D games, anyone got any ideas how i can have certain sprites only visible if you have an aura item or something, see the pic for what i mean
