Seamless Gravel 027 by Textures is a meticulously crafted PBR 3D texture designed to authentically replicate the natural composition and appearance of gravel surfaces with exceptional realism. This texture faithfully captures the granular complexity of mineral-based aggregates primarily composed of small stone pebbles and coarse dirt particles all naturally bound together by fine sediment and organic soil matter. Its surface finish exhibits a slightly rough weathered look typical of outdoor ground covered with loose gravel featuring subtle variations in porosity and grain orientation that affect how light interacts with the material. The color palette consists of earthy yellow and brown tones reflecting mineral oxides and organic dirt residues which together create a dynamic and natural-looking base substrate ideal for any 3D environment.

The extensive material detail is accurately conveyed across all essential PBR channels to deliver a realistic rendering experience. The Base Color (Albedo) map showcases the nuanced yellowish gravel and dirt hues while the Normal map simulates the intricate surface relief of stones and soil granules adding depth and tactile quality. The Roughness map defines the non-uniform matte finish common to natural gravel preventing any unwanted glossiness and preserving the authentic weathered texture. Ambient Occlusion enhances subtle shadowing within the crevices between pebbles increasing the perception of depth and complexity. Height and displacement maps allow for enhanced surface detail and parallax effects mimicking the uneven terrain of gravel beds without disrupting seamless tiling. The texture is non-metallic reflecting the organic and mineral composition faithfully across various rendering engines.

Seamless Gravel 027 is fully tileable and optimized for physically based rendering workflows ensuring consistent shading and natural appearance across large surfaces without visible seams. It is ready for use in Blender with the Principled BSDF shader Unreal Engine utilizing Base Color Roughness Normal and Ambient Occlusion maps and Unity’s URP/HDRP pipelines through the Lit shader. The included 8K resolution assets guarantee crisp detail and high fidelity suitable for both close-up renders and expansive outdoor environments. For best results maintain a consistent UV scale to preserve texel density and consider carefully tuning roughness values to match specific lighting conditions. Experimenting with height or parallax mapping can further enhance the perceived depth and realism of gravel surfaces particularly in scenes requiring high visual detail.

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.
