The coarse oak bark texture seamless high resolution up to 8k presents an organic surface characterized by rugged, fibrous wood substrate with natural weathering effects. The bark’s composition reflects layers of dense cellulose fibers and lignin, interspersed with slight porosity and fissures formed through years of growth and exposure to environmental elements. This texture captures the rough, uneven grain orientation typical of oak bark, featuring flaky segments and a matte finish that absorbs light variably. Subtle pigment variations, ranging from deep browns to muted grays, simulate the natural oxidation and pigment deposits found in aged bark, enhancing the authenticity of the surface. This material’s physical realism is conveyed through a complex interplay of colorants and microgeometry, representing the bark’s coarse, tactile feel and visual depth.
In terms of physically based rendering (PBR) channels, the BaseColor or Albedo map accurately reproduces the nuanced color palette with mid-to-dark browns and subtle tonal shifts, avoiding any metallic hints to preserve the organic wood appearance. The Normal map encodes the intricate surface relief and grain orientation, emphasizing the bark’s depth and natural roughness. Roughness is moderately high, reflecting the uneven, matte texture that scatters light diffusely without glossiness, while the Metallic channel remains at zero, consistent with the non-metallic nature of organic bark. Ambient Occlusion enhances shadowed crevices and fissures, adding visual weight and realism, whereas the Height or Displacement map captures the bark’s relief, enabling realistic parallax and depth effects in 3D environments.
This tileable coarse oak bark texture seamless high resolution up to 8k is expertly crafted to integrate seamlessly into modern digital content creation pipelines, supporting software such as Blender, Unreal Engine, and Unity. The ultra-high resolution ensures crisp detail even on extensive UV islands, making it suitable for real-time scenes, cinematic renders, and environmental level dressing. For optimal results, it is advisable to maintain consistent texel density across assets and carefully scale UV maps to prevent distortion and stretching. Additionally, adjusting roughness parameters can help fine-tune the visual response under different lighting conditions, enhancing realism in both close-up and distant views.
This AI-generated coarse oak bark texture seamless high resolution up to 8k offers detailed bark textures with a natural coarse oak bark texture seamless high resolution up to 8k appearance, ideal for accurate 3D preview and PBR material applications.
How to Use These Seamless PBR Textures in Blender
This guide shows how to connect a full PBR texture set to Principled BSDF in Blender (Cycles or Eevee). Works with any of our seamless textures free download, including PBR PNG materials for Blender / Unreal / Unity.
What’s inside the download
*_albedo.png — Base Color (sRGB)*_normal.png — Normal map (Non-Color)*_roughness.png — Roughness (Non-Color)*_metallic.png — Metallic (Non-Color)*_ao.png — Ambient Occlusion (Non-Color)*_height.png — Height / Displacement (Non-Color)*_ORM.png — Packed map (R=AO, G=Roughness, B=Metallic, Non-Color)
Quick start (Node Wrangler, 30 seconds)
- Enable the addon: Edit → Preferences → Add-ons → Node Wrangler.
- Create a material and select the Principled BSDF node.
- Press Ctrl + Shift + T and select the maps
albedo, normal, roughness, metallic (skip height and ORM for now) → Open.
The addon wires Base Color, Normal (with a Normal Map node), Roughness, and Metallic automatically.
- Add AO and Height using the “Manual wiring” steps below (5 and 6).
Manual wiring (full control)
- Create a material (Material Properties → New) and open the Shader Editor.
- Add an Image Texture node for each map. Set Color Space:
- Albedo → sRGB
- AO, Roughness, Metallic, Normal, Height, ORM → Non-Color
- Connect to Principled BSDF:
albedo → Base Colorroughness → Roughnessmetallic → Metallic (for wood this often stays near 0)normal → Normal Map node (Type: Tangent Space) → Normal of Principled.
If details look “inverted”, enable Invert Y on the Normal Map node.
- Ambient Occlusion (AO):
- Add a MixRGB (or Mix Color) node in mode Multiply.
- Input A =
albedo, Input B = ao, Factor = 1.0.
- Output of Mix → Base Color of Principled (replaces the direct albedo connection).
- Height / Displacement:
Cycles — true displacement
- Material Properties → Settings → Displacement: Displacement and Bump.
- Add a Displacement node: connect
height → Height, set Midlevel = 0.5, Scale = 0.02–0.08 (tune to taste).
- Output of Displacement → Material Output → Displacement.
- Add geometry density (e.g., Subdivision Surface) so displacement has polygons to work with.
Eevee (or lightweight Cycles) — bump only
- Add a Bump node:
height → Height.
- Set Strength = 0.2–0.5, Distance = 0.05–0.1, and connect Normal output to Principled’s Normal.
Using the packed ORM texture (optional)
Instead of separate AO/Roughness/Metallic maps you can use the single *_ORM.png:
- Add one Image Texture (Non-Color) → Separate RGB (or Separate Color).
- R (red) → AO (use it in the Multiply node with albedo as above).
- G (green) → Roughness of Principled.
- B (blue) → Metallic of Principled.
UVs & seamless tiling
- These textures are seamless. If your mesh has no UVs, go to UV Editing → Smart UV Project.
- For scale/repeat, add Texture Coordinate (UV) → Mapping and plug it into all texture nodes.
Increase Mapping → Scale (e.g., 2/2/2) to tile more densely.
Recommended starter values
- Normal Map Strength: 0.5–1.0
- Bump Strength: ~0.3
- Displacement Scale (Cycles): ~0.03
Common pitfalls
- Wrong Color Space (normals/roughness/etc. must be Non-Color).
- “Inverted” details → enable Invert Y on the Normal Map node.
- Over-strong relief → lower Displacement Scale or Bump Strength.
