I have done a couple relights of the Sequencer level provided by Epic Games. This project started off as a test of how I dramatically could I change the lighting, tone and atmosphere to suit different games while still keeping the content mostly the same.
However, it then turned into a test of using Ray Tracing in UE4 for the first time which is fairly easy to get the hang of but not having an RTX graphics card makes the frame rate awful and really hard to manoeuvre round the level. Ray Tracing is also in its infancy so it undoubtedly going to improve but even using my GTX 1080 it struggles with frequent crashes etc.
The first relight was mainly focused around CyberPunk 2077 and influenced by the music video for "Walk Man" by TMG.
The Second relight was focused around Bioshock as I haven't attempted to light anything using that colour palette of blues and greens before and it was an interesting change.
