Created as a submission to Pwnisher's Render challenge. Insides of the train compartments mostly textured with substance, rest is from quixel library, mixed together in shader editor.
Rendered as four part, past scene and present day scene and both inside the compartment and outside later composited together. Snow in the first shot is a 2d black on white stock video. Rain drops on the window is procedurally generated and layered on top of existent glass material.
