Painted metal with chips, rust and streaks

Weathered painted metal in layers: paint chips away in noisy patches to show bare metal, rust grows around the chips, and rust streaks run downward in world space below them.

Parameters
paint_color (vec4 = 0.2, 0.42, 0.35, 1), metal_color (vec4 = 0.62, 0.62, 0.64, 1), rust_color (vec4 = 0.48, 0.22, 0.08, 1), rust_dark (vec4 = 0.22, 0.1, 0.05, 1), scale (float = 4), chipping (float = 0.35), rust_spread (float = 0.12), streak_amount (float = 0.5) and 1 more

Limits to consider

Wear is placed by noise, not by edges or cavities, so it does not favour corners. World-space masks slide over moving objects; switch to object space for props that move. No relief between paint and metal.
