Capture the character of mature tree bark with a tileable 4K PBR texture featuring deep vertical furrows, flaky ridges, and subtle cross‑grain scarring for convincing close‑ups. The set includes BaseColor, Normal, Roughness, and Ambient Occlusion maps authored for stable shading across real‑time engines and offline renderers, with mid‑range roughness for natural, matte specular roll‑off. Normal detail emphasizes layered bark plates and chipped edges, while AO strengthens crevice depth without over‑darkening when lit by HDRIs or directional sun. Seamless tiling supports large trunks, forest assets, stylized realism, and nature environment dressing without visible repeats at typical camera distances. The color palette is a neutral brown‑gray that grades well and avoids green or red color casts, ensuring compatibility with diverse biomes. Works out‑of‑the‑box with Blender Principled BSDF, Unreal, Unity, V‑Ray, Arnold, Redshift, Octane, and Houdini. Recommended real‑world scale sets one tile to ≈1×1 m; adjust UVs for trunk circumference continuity. Delivered as PNGs (BC/NRM/RGH/AO) with linear maps in non‑sRGB where appropriate, plus a quick README for shader hookup, packed variants (ORM/RMA) on request.
