Hello, I was wondering if it is possible to make a level in the editor that includes a popup menu on a button press that lists a set of items, and not only lets you place them (with editable snaps), but scale them, select/modify materials or material instances, and add basic blueprints IN-GAME, but saving it as a map to use later. Similar to how Forge in halo works, but slightly improved. Basically what I want is to transfer all the map-making capabilities of the editor into a game, so I can send it to a friend to have him make levels he can play on, or just to use myself to create levels with a controller. Is this possible, and if so, what would be the best way to go about it? If you would rather link to some other post than explain, that works for me, but I have not been able to find much myself.
EDIT: If I can manage to get this going, I would like the ability to select seasons, or themes, either globally or by object, to modify materials. Example, if I have an airport as a map, when you change the season globally to winter, there will be a different material for the tarmac to have snow on it, blocks placed will have snow or ice on the upper regions, and everything will be somewhat more blue.
