Disowned was made three years ago in Unreal Engine 4. Back then, we did not have Nanite or Lumen, but it had ray-traced shadows and reflections as its brand new feature. I wanted to try it out. It was possible to build UE4 from source with Nvidia RTX features enabled, which gave me access to Dynamic Global Illumination. I used these along with Unreal’s then new in-engine modeling tools to bring Disowned to life.
