A heavy equipment shovel used in oil sands I modeled in 2018 for a VR inspection tool. It is the most detailed individual object I have ever modeled rivaling full environments in complexity.

I collaborated with Tyler Forseth-Agnew on this project. He built all the interior except for the cab and the exterior parts highlighted in green on the last image. Check out his page at tinman.artstation.com
