Seamless Gravel 031 by Textures is a meticulously crafted high-resolution PBR 3D texture designed to authentically replicate the natural characteristics of outdoor gravel surfaces. The material composition simulates a mineral-rich aggregate primarily composed of small irregularly shaped stones loosely bound by fine sediment and organic matter typical of weathered gravel beds found in nature. The color palette features subtle yellowish earth tones that evoke sun-worn gravel substrates enhanced by natural variations in pigment concentration and oxide layers that contribute to the realistic surface finish. This texture captures the porous and rough qualities of gravel with weathered edges and a matte non-reflective finish that prevents unnatural glossiness making it ideal for ground pathway or landscape materials in 3D environments.

Each PBR channel is carefully developed to convey the physical properties of the gravel surface for consistent and realistic shading across modern rendering engines. The Base Color (Albedo) map presents the natural yellowish hues and subtle mineral variations while the Normal map accurately reproduces the intricate surface relief of individual stones and fine sediment gaps enhancing depth perception. The Roughness channel controls the non-metallic gritty surface finish reflecting the uneven texture typical of outdoor gravel. Ambient Occlusion adds realistic shading to crevices between stones emphasizing depth and dimensionality. The Height (Displacement) map enables enhanced parallax and geometric detail on supported platforms increasing realism in close-up views. The Metallic channel is omitted reflecting gravel’s inherently non-metallic nature.

Seamless Gravel 031 is optimized for physically based rendering workflows and fully compatible with Blender’s Principled BSDF shader Unreal Engine (using Base Color Roughness Normal and AO inputs) and Unity’s URP and HDRP Lit shaders. The texture tiles seamlessly across large surfaces without visible seams maintaining consistent texel density and shading fidelity even at resolutions up to 8K making it suitable for highly detailed close-up renders or expansive environments. For best results it is recommended to maintain consistent UV texel density and consider combining the Normal map with Height or Parallax effects to enhance depth perception and surface detail ensuring a natural and believable gravel appearance in any 3D scene.

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.
