Seamless Gravel 008 by Textures is a high-quality PBR 3D texture expertly designed to replicate the intricate composition of natural gravel surfaces with remarkable realism. This texture captures an organic substrate typical of weathered gravel beds featuring a complex mixture of small river pebbles and granular stone aggregates intricately bound together by fine mineral sediments. The surface exhibits a slightly rough unpolished finish that reflects subtle variations in porosity and natural wear caused by prolonged environmental exposure. Coloration is dominated by muted grey tones interspersed with earthy hues created through a nuanced blend of pigments and oxide layers lending depth and authenticity to the base color (albedo) channel. This delicate interplay of materials is meticulously represented across all PBR maps to support physically based shading workflows in modern 3D rendering engines.

The Base Color (Albedo) channel delivers precise color gradients and subtle pigment dispersions without embedded lighting faithfully portraying the natural stone’s tonal complexity. The Normal map enhances the three-dimensional characteristics of the gravel by accentuating pebble contours and surface irregularities resulting in realistic light interaction and shadowing. Roughness values are carefully balanced to simulate the diffuse reflection of a natural stone surface combining matte and slightly glossy areas that mimic weathered textures. The Ambient Occlusion channel adds visual depth by simulating soft shadows within crevices between stones while the Height/Displacement map provides accurate surface relief for advanced parallax occlusion or displacement techniques. Metallic content is minimal reflecting the non-metallic mineral composition of gravel and ensuring correct diffuse reflections without artificial specular highlights.

This texture is fully optimized for seamless tiling ensuring consistent shading and eliminating visible repetition when applied over extensive surfaces. It supports ultra-high resolution up to 8K delivering crisp detail even in close-up renders. Seamless Gravel 008 is compatible with major 3D software and engines such as Blender (using Principled BSDF) Unreal Engine (utilizing Base Color Roughness Normal and Ambient Occlusion maps) and Unity’s URP or HDRP pipelines through the Lit shader. For optimal results maintain consistent UV texel density across your models and consider using triplanar or layered tiling methods to further minimize pattern repetition. Combining the Normal map with Height or Parallax occlusion techniques can significantly enhance depth perception and surface realism while importing color textures as sRGB and data maps as Non-Color ensures proper color management throughout your shading workflow.

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)

  1. Enable the addon: Edit → Preferences → Add-ons → Node Wrangler.
  2. Create a material and select the Principled BSDF node.
  3. 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.
  4. Add AO and Height using the “Manual wiring” steps below (5 and 6).

Manual wiring (full control)

  1. Create a material (Material Properties → New) and open the Shader Editor.
  2. Add an Image Texture node for each map. Set Color Space:
    • AlbedosRGB
    • AO, Roughness, Metallic, Normal, Height, ORMNon-Color
  3. Connect to Principled BSDF:
    • albedoBase Color
    • roughnessRoughness
    • metallicMetallic (for wood this often stays near 0)
    • normalNormal Map node (Type: Tangent Space) → Normal of Principled. If details look “inverted”, enable Invert Y on the Normal Map node.
  4. 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).
  5. Height / Displacement:
    Cycles — true displacement
    1. Material Properties → SettingsDisplacement: Displacement and Bump.
    2. Add a Displacement node: connect heightHeight, set Midlevel = 0.5, Scale = 0.02–0.08 (tune to taste).
    3. Output of Displacement → Material Output → Displacement.
    4. Add geometry density (e.g., Subdivision Surface) so displacement has polygons to work with.
    Eevee (or lightweight Cycles) — bump only
    1. Add a Bump node: heightHeight.
    2. 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:

  1. Add one Image Texture (Non-Color) → Separate RGB (or Separate Color).
  2. R (red) → AO (use it in the Multiply node with albedo as above).
  3. G (green) → Roughness of Principled.
  4. B (blue) → Metallic of Principled.

UVs & seamless tiling

  1. These textures are seamless. If your mesh has no UVs, go to UV EditingSmart UV Project.
  2. 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.
