Object with same functionality as Sign barricades, but for map editor. These could be used to add street names, direction signs, graffiti, anything. Just make it so that when you spawn it, it says some default text like “Preview”, and when you select it there is a text field on the left bottom part of the screen, just like the material palette selection one, where you can type your text.
So far the only way to add such things to a map is either to make individual objects for each, or make like 60 separate decals for each symbol, and then arrange them on blank sign objects. Both options are tedious, and dont let people who only do mapping and not modding make custom text assets for their maps. And the sign code is already in the game, so it shouldn’t take much effort to add this new kind of asset.
