Bring natural character to trunks, logs, and forest assets with a tileable 4K PBR bark material featuring deep diagonal furrows, layered plates, and organically formed knots. The BaseColor preserves neutral warm‑brown values with subtle lichen tinting in crevices, grading cleanly across daylight and overcast HDRIs. The Normal map captures pronounced ridge depth, chipped plate edges, and micro relief so highlights read convincingly at grazing angles in both real‑time and offline renderers. Roughness is authored as dry bark—matte overall with slight variation across ridges—preventing plastic sheen while maintaining breakup. AO strengthens crevice depth and knot cavities without crushing shadows, enabling robust look‑dev in Unreal, Unity, Blender, and V‑Ray/Arnold/Redshift/Octane pipelines. Seamless tiling supports large trunks and stumps without obvious repeats at typical camera distances; recommended scale is ≈1×1 m per tile with plates sized for mid‑to‑large trees. Delivered at 4096×4096 as BaseColor, Normal (OpenGL), Roughness, and AO; packed ORM/RMA variants available on request. Ideal for realistic games, films, and archviz greenery where readable bark structure adds storytelling detail. Licensed for commercial use; redistribution of raw files is not permitted.
