This seamless 3D texture in 8K resolution authentically represents volcanic ash ground interspersed with scattered charcoal fragments and patches of dry soil. The base substrate is a fine, powdery volcanic ash composed primarily of silicate minerals, lending a crumbly and soft organic feel typical of post-eruption terrain. Charcoal fragments, dark and porous, add organic carbonaceous inclusions that contrast with the pale gray and brown hues of the ash and dry earth. Weathering effects are evident in the uneven surface topology, where erosion and settling create natural depressions and roughness. The surface finish mimics a matte, unpolished soil layer with subtle variations in grain orientation and porosity that contribute to its realistic tactile impression.
In PBR workflows, this material’s BaseColor map captures the muted earth tones with charcoal blacks and dusty grays, while the Normal map accentuates the fine granular detail and subtle unevenness of the terrain. The Roughness channel reflects the soft, powdery texture of volcanic ash, offering moderate reflectivity with non-metallic characteristics, and the Metallic channel remains near zero, consistent with the organic, mineral-based composition. Ambient Occlusion enhances the depth of crevices and charcoal fragments, providing natural shadowing without artificial lighting, and the Height/Displacement map enables precise relief for enhanced realism in close-up renders.
Optimized for seamless tiling, this volcanic ash PBR texture is ready for integration into Blender, Unreal Engine, and Unity projects, supporting high-fidelity 3D visualization and gaming environments. Its neutral, flat lighting setup ensures adaptability across diverse lighting scenarios without unwanted shadows or embedded text. For practical application, adjusting UV scale to balance detail density and fine-tuning roughness can help achieve the ideal surface interaction under various scene lighting conditions, while height map utilization enhances depth perception in virtual terrains.
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

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 Color
roughness
→ Roughness
metallic
→ 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.
