I didn't run into any errors after following the tutorial instructions to create a level and place a character into it. When it got to the point of toggling in and out of "Game Mode" I've run into trouble. When I go into Game Mode the game screen is black, save for the UI elements. I loaded up the Cow module in the editor and was able to see everything without issue when I went into Game Mode. So, I'm not sure what's causing that problem in my module. Is the default lighting not enough to light the scene? Has anyone else run into this?
