nml_mud_roughness

Generated from: Seamless tileable grayscale roughness map, no colour, no lighting, no shadows, no text, no watermark, brightness equals surface roughness only, 4096x4096. Surface: wet churned liquid mud on a World War One battlefield. Standing rain water and saturated sludge read smooth and dark (low roughness, near black), drier crusted mud ridges and clods read uneven and bright (high roughness, light grey), scattered wet and dry patches evenly distributed over the whole frame with no focal feature and no large contiguous bright or dark region. Mostly mid grey with fine varied mottling. Perfectly seamless: left edge matches right edge, top edge matches bottom edge. Technical game PBR roughness map.
