A photoreal, seamless bark material capturing the rugged ridges of mature oak with natural moss growth and subtle lichen speckling for richly detailed forests, dioramas, and close‑up hero shots in games and film. Authored for the metal/rough PBR workflow, the pack includes calibrated 4K maps—Albedo/Base Color with neutral lighting, Normal for crisp fissures and layered bark plates, Roughness tuned for dry bark with damp moss variation, Height/Displacement for deep crevice relief, and Ambient Occlusion for grounded micro‑shadowing—organized with consistent filenames for plug‑and‑play import into major DCCs and engines. All textures are square, power‑of‑two, and tile seamlessly around trunks or on large surfaces without visible repeats, preserving fine fiber strands, moss clumps, and edge breakup at close range. Use parallax or true displacement to emphasize plate lift and vertical ridges, and art‑direct the moss intensity via Albedo and Roughness for seasonal looks from dry summer to damp spring. Following proven listing practices, previews include sphere and tiled planes with clear, concise specs to maximize marketplace search visibility and buyer confidence. Deliverables: 4096×4096 PNGs—BaseColor, Normal, Roughness, Height, AO—fully tileable and production ready.​
