A realistic weathered concrete material with natural moss growth and organic dirt accumulation, designed to represent aged outdoor surfaces exposed to moisture and time. The material features subtle concrete roughness combined with irregular moss patches, creating an authentic worn appearance commonly found on old walls, pavements, foundations, and abandoned structures. uilt using a fully procedural node setup, this material provides clean tiling, seamless transitions, and flexible control over surface variation. The moss distribution appears naturally clustered, avoiding repetition and enhancing realism across large surfaces. The shader delivers accurate roughness variation, soft height detail, and natural color blending, making it suitable for both close-up renders and large-scale environments.
