I have Unity 5 and when I make a new project, there are no assets that are usually there (Character Controller, Terrain, etc.). How do I fix that?
Go to http://unity3d.com/get-unity/download?ref=personal click on "ADDITIONAL DOWNLOADS FOR WINDOWS" and select "Standard Assets".
Window from the top menu, and open the
Asset Store. On the right hand side of the page there is a list of categories. Select the
Unity Essentials category. This category contains a number of asset packages published by Unity Technologies. Included in this pack is the
Standard Assets package.
You'll also find a number of other packages that have great quality assets and they're all free.
