Key Features

Age your whole scene in one click -- add one renderer feature and one volume override, then raise a slider
Five effects -- dirt, dust, moss, metal aging and rust, each with its own colors, size, coverage and placement rules
Smart placement -- dust settles where it would fall, dirt gathers where rain never washes it away, moss and rust favor the sheltered side
Metal aware -- aging and corrosion reach only metallic surfaces, driven by the metalness your GBuffer already holds
Real PBR deposits -- moss and rust bring their own color, roughness and relief, anchored in world space
Color variation breaks the repetitive look of large surfaces, and bioluminescent moss adds HDR emission ready for Bloom
Dry, Grimy and Abandoned presets, zones with soft borders, and per-object components to anchor, clean or restyle anything
One master Intensity slider drives the whole effect, even from script -- for URP on Unity 6.1 or newer
