For this tutorial, we'll use a level preconfigured for the best results with Enlighten. This is a good way to see what Enlighten can do.

1. Under Viewport Options (the drop-down menu in the top-left of the game view), make sure Realtime is enabled. This means you'll see Enlighten updates in real time.
   

2. In Unreal Editor, in the Content Drawer, in Enlighten > Maps, open the level Tutorial_First.
   
   Unreal Editor opens the level.

   A warning may show up "Repaired painted vertex colors in 0.0s for 2 components in /Game/Enlighten/Maps/Tutorial_First. Resave map to fix.".

3. Make sure the View Mode is set to Lit. This means we can see the changes to the lighting we're going to make.
