Had the pleasure of creating this 2-hour workshop on lighting for Gnomon! It covers all the workflows I personally use when lighting and creating cinematics inside unreal 5, from GPU Lightmass baking to shot lighting cinematics using lumen. Check it out if you want to get a better insight into how I approach lighting in unreal and hopefully by the end, you'll have some helpful takeaways from my workflow that you can incorporate into your own.
