One of my current projects: An asteroid mining and smelting facility in deep space.
This Unreal environment was built from a small asset kit I created and detailed with two trimsheets. I still have to do a full texture pass aswell as create assets for asteroids and the mechanisms used to guide rocks into the facility and break them down.
The HDRI and Astronaut were the only thing not created by me in the scene.
HDRI was taken from https://www.spacespheremaps.com/hdr-spheremaps/
Astronaut mesh was taken from https://sketchfab.com/3d-models/rust-space-suit-c9b05b4878d64c68945ba8858c523a68
