Quick render comparing the newly updated Principle BSDF 2.0 with energy conservation of Blender 4.0 to the legacy Principle BSDF from the older versions. I could easily see the huge difference, especially with metallic materials. The Pedals were textured by me with Substance Painter and Photoshop, most of other models are from Sketchfab free, CC attribution assets ( I planned to create everything myself but I’m just too tired from lack of sleep and don’t want to waste weeks making some proper assets for a quick and dirty render and never touch them again even though I could). Scroll down to see my smart rust material and the comparison video.
