This is my first Unreal Engine 5 project and I decided to recreate my favourite scene from God of War. I worked with Lumen and Nanite to achieve a more realistic look of the level. All assets (except the megascans) were created by myself with Zbrush, 3ds Max etc. Working with UE5 has opened up so many new worlds, many probably still unknown to me. 
Personally, the Environment Production tutorial from Artstation Learning helped me a lot. I was able to learn many new things and apply them immediately.
