After prepping our model it's time to run those scripts that we downloaded and loaded. The first will allow us to flatten the UV maps so that shadow and light information can be baked into the object. Without this script this is a tedious process. The second exports each item as a seperate FBX file which helps when importing into Unreal Engine. It also allows us to copy the objects location to the clipboard which allows us to simply copy and paste the objects into our scene.
Here are the links to the SteamRoller and TS_Tools scripts. The Load Scripts video explains how to install them.
