It is possible in the sim world train livery mode to be able to group a certain number of decals together. This mainly allows you to be able to move a large number of decals between them or create groups of logos. 1. What would the “save decal group” option consist of? (possible name of the prototype) this option would make it possible to reuse groups of decals created on one train for reuse on many other trains or wagons. These saved decal groups could appear in a tab: “Personal Decal Group” or “Saved Group” in the Livery Designer. 2. When appearing on other trains how would this appear? When the decal group appears on another train or car, 2 options could be implemented : (1) it would still be possible to modify the group of decals by each decal separately (color, size, shape). (2) it would only be possible to modify only the size, angle of the group of decals and so it would be considered as a single decal.
