This is a collection of prefabs from Sof2. All files are in .map format. To use unzip the files into a local directory. Open your editor, then simply go to Edit > Load Prefab - and select the .map prefab to load.
The prefabs use the texture directory for the name. Therefore if you would like to see the texture used or modify the prefab, simply load the texture and find the texture name as used for the prefab name: ex: airport_toolbox.map - Load the airport textures and find the texture named toolbox.
All files here-in are free to use without need to give me credit. These are included in all editors so I can't claim them as mine. :-)
