nml_timber_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: rotted wet timber from a World War One trench, split plank and duckboard faces. Mostly light grey rough weathered grain and splintered fibre, broken by darker smoother bands where rain water has soaked and darkened the wood, evenly distributed over the whole frame with no focal feature and no large contiguous region. Fine varied mottling. Perfectly seamless: left edge matches right edge, top edge matches bottom edge. Technical game PBR roughness map.
