Seamless Gravel 014 by Textures is a meticulously crafted high-quality PBR 3D texture designed to authentically replicate the natural complexity of gravel surfaces. This texture embodies a loosely compacted substrate composed of small rock fragments naturally occurring mineral aggregates and fine sandy particles bonded together to form a realistic granular composition. The surface reveals subtle variations in porosity and weathering capturing the effects of organic erosion and sediment deposition over time. Its color palette is achieved through a blend of earthy pigments and oxide layers resulting in a harmonious mix of muted grays browns and sandy hues that enhance the tactile and visual realism of outdoor gravel. The finish is slightly rough and matte typical of natural gravel with delicate micro-roughness variations that lend authenticity to the texture’s surface feel.

In physically based rendering workflows this texture excels by delivering accurate shading and material representation across all PBR channels. The Base Color (Albedo) map faithfully presents the intricate distribution of stones and sandy aggregates without any baked-in lighting allowing for flexible scene illumination. The Normal map provides detailed surface relief simulating the unevenness and granular nature of gravel with precision. Roughness maps subtly vary to reflect natural differences in surface glossiness from smoother pebbles to coarser mineral grains while the Metallic channel is consistently zero as the material is purely non-metallic. Ambient Occlusion enhances depth and spatial perception by emphasizing crevices and shadowed areas between fragments. Height and Displacement maps further enhance realism by enabling geometry displacement in supported engines creating a convincing sense of depth and dimensionality.

Optimized for seamless tiling and supporting resolutions up to 8K this texture is ideal for large surface coverage in modern rendering engines such as Blender Unreal Engine and Unity. For Blender it pairs effectively with the Principled BSDF shader while Unreal Engine workflows benefit from correctly connecting the Base Color Roughness Normal and Ambient Occlusion maps. In Unity’s URP and HDRP pipelines these maps integrate smoothly with the Lit shader for realistic material rendering. To maintain consistent detail and avoid visible repetition it’s recommended to use triplanar or layered tiling techniques alongside consistent texel density. Additionally combining the Normal map with height or parallax occlusion mapping enhances tactile perception by introducing subtle depth shifts without increasing mesh complexity making this texture a versatile and practical choice for creating highly realistic gravel surfaces in any 3D project.

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.
