Hi Elliott, This is a great breakdown and very generous in sharing your process and insights, you came a long way from the vending machine days!
Are you planning on releasing the UE4 project to the public? Or only builds? I'd love to play around with it in the editor if possible!
Unreal Engine 4: Flowstone Cave VR Project
This is a virtual reality project created in Unreal Engine 4. It allows users to explore the depths of a dark cave using a flashlight and works best with the Rift DK2. The project was modeled by the game designer Jan Kaluza who runs a developer blog and a website called Broad Strokes. He previously created the Over 9000 Swords modular weapon system with Lee Devonald. It allows users to create thousands of sword variations for their projects.
