 ## Assets ##
 
-- **[ReportUnusedAssets.py](https://github.com/mamoniem/UnrealEditorPythonScripts/blob/master/Assets/ReportUnusedAssets.py)** Running this script will look through all the project folders, and add to the log the assets that were found not in a use, or in another work, the assets that have no dependency with any other project files.

The number of the final generated instances count can be set within the script before running, by changing the value of the variable *totalRequiredInstances*
