Hi i am new to the modding side of things for Emergency 4 and i was wondering how do i add a custom map into the editor? i downloaded a map texture off this website. and i do not know how to add it if any could help that would be great. and second i having trouble with the create new mod in the editor when i make a new mod it says it has successfully been created but when i check my mods folder in the game directory the mod folder is not there. if anyone could help with these two problems that would be great.
