This model is intended for usage with the program, Blender, and comes in two versions. The Cycles version uses Blender's ray-tracing render engine. It takes a long time to render but provides the most realism. The Eevee version uses Blender's real-time render engine. It renders roughly 7 times faster, but provides much less realism.
I encourage people to use or modify this model for whatever they wish. My only request is that credit is given in post descriptions.
