I want to know if any one knows a site were I can get free ready made buildings.
I would also appresiate if someone could tell me a free program to make buldings, Maya and Cheter and cinima 4d take 3-4 hours to download so somthing else pease.
I suggest you should try out Google Sketchup or Blender3D. Google Sketchup is an easy-to-use program that will allow you to make buildings in seconds. You can export models from sketchup to Unity3D. Blender is a powerful open source modeling tool you can use if you have modeling experience. Turbosquid.com may have some free models you can use.
