Do anyone know if it’s any point in deleting unused images, objects and scenes, or will the unused stuff be removed from the compiled game anyway?
All images, objects and scenes will be included in the compiled game, even if they are not used. ( Even if they won’t decrase performances, they will make the game bigger ).
However, there is a button in the ribbon of the image bank editor so as to display a list of unused resources, with the possibility to delete them by checking them in the list.
