I started making a game today, and I was halfway through the third level when I realised that shadows caused “Preview” to show up. I don’t know if this means that we can’t use these in our commecial projects or if it means that it will go away after packing.
That just means your lighting isn’t built. At the top where the build button is, click the drop down and you can select build lighting. Which will process the real lighting and remove “preview” from the shadows.
Yep, you’re allowed to use any of the content released by Epic Games in commercial projects. You’ll need to build the lighting.
Oh, got it
