This is Tree Bark Texture, a Rough PBR material captured at close range and tuned for accuracy. Base color, surface normal and roughness arrive in register, backed by the usual supporting passes. Built at 4K, the surface keeps its grain and micro-relief when pushed in tight. Perfect for floorboards, barrels and weathered fences with honest wear and tone. The naming and channels follow convention, dropping neatly into Blender, Unreal Engine and Unity. Drop it in, light it, and move on, exactly what a production material should do.
