Seamless Gravel 034 by Textures is a meticulously crafted high-resolution PBR 3D texture that authentically captures the intricate complexity and ruggedness of natural gravel surfaces. This texture represents a granular aggregate composed primarily of small mineral stones naturally bound together by fine sediment and subtle organic matter. The composition creates a highly realistic substrate often found in outdoor ground coverings such as walkways driveways and landscaping features. Its surface exhibits gentle porosity and distinct weathering effects with scattered dirt particles and slight variations in grain size and orientation all of which contribute to an organic and believable appearance. The finish is matte with a lightly rough tactile quality that emphasizes the unpolished natural state typical of gravel. Color variations emerge from an earthy blend of pigments and oxide layers ranging from muted grays and browns to faint reddish tones accurately reflected in the Base Color (Albedo) channel to ensure lifelike shading and seamless integration into diverse 3D environments.

The PBR workflow integration of this texture is optimized for consistent and predictable shading across major rendering engines such as Blender Unreal Engine and Unity. The Normal map encodes fine surface details and micro-roughness from the mineral grains enhancing depth perception and realism without the need for heavy geometry. The Roughness map carefully controls reflectivity reinforcing the naturally matte non-metallic character of gravel aggregates while the Metallic map remains flat as expected for natural mineral substrates. Ambient Occlusion (AO) effectively highlights crevices and contact shadows between the stones adding depth and grounding the texture convincingly within 3D scenes. Height or Displacement maps provide subtle surface relief ideal for use with parallax occlusion or tessellation techniques to accentuate the texture’s rugged topography and three-dimensional feel.

Offered at an impressive resolution of up to 8K this seamless texture ensures exceptional detail and clarity even on large-scale surfaces eliminating visible tiling artifacts and maintaining realism across extensive terrains or architectural elements. It is fully compatible with Blender’s Principled BSDF shader Unreal Engine’s physically based workflow by connecting Base Color Roughness Normal and AO maps as well as Unity’s URP and HDRP pipelines using the Lit shader. For optimal results it is recommended to maintain consistent texel density when adjusting UV coordinates to avoid stretching or blurring. A practical tip for enhancing visual depth and minimizing repetition especially in close-up renders is to combine the Normal map with Height or Parallax Occlusion mapping which further enriches the perception of surface complexity and natural variation.

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.
