This seamless 8K PBR texture represents tuff, a naturally occurring sedimentary rock distinguished by its porous and rough surface. Formed through the consolidation of volcanic ash and fragmented rock particles, tuff exhibits a heterogeneous composition where fine-grained volcanic glass and mineral fragments act as the substrate. These constituents are bound together by naturally occurring silica and calcium carbonate cements, creating a solid yet porous matrix. The texture highlights the characteristic graininess and irregular pore distribution, resulting from weathering processes that enhance its depth and tactile complexity. Its geometric form is irregular and non-repetitive, mimicking natural rock faces and stone walls without the influence of human-made patterns, making it ideal for authentic natural environments.
Visually, the texture’s surface finish is rough and matte, reflecting minimal reflectivity with subtle light scatter due to its porous nature. The color palette ranges from earthy beige and gray tones to muted browns, shaped by mineral impurities and weathered oxidation. This variation is captured in the BaseColor (Albedo) channel, providing realistic color gradations without artificial saturation. The Normal map accentuates the uneven surface geometry and micro-details of the porous stone, while the Roughness channel defines the coarse, non-glossy finish that diffuses light softly. The Metallic channel remains near zero, as tuff is non-metallic, whereas Ambient Occlusion enhances the perception of depth within crevices and pores. Height and Displacement maps simulate the tactile roughness and subtle relief of weathered rock surfaces, enabling enhanced realism in 3D renders.
Designed for compatibility with Blender, Unreal Engine, and Unity, this 8K texture ensures high fidelity and close-up detail without pixelation. The seamless nature allows for large surface tiling without visible repetition, essential for expansive rock faces or stone wall applications. For optimal results, it is advisable to adjust the UV scale to maintain the natural grain size relative to the model’s proportions. Additionally, fine-tuning the Roughness channel can help adapt the material to varying lighting environments, while blending Height or Parallax maps with Normal maps enhances the visual depth and structural complexity when viewed at oblique angles.
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.
