This seamless 3D texture in ultra-high 8K resolution presents a granular gravel bed primarily composed of angular to sub-rounded limestone gravel combined with fine gravel grains delivering exceptional detail and realism for outdoor environments. The base substrate features natural mineral aggregates of limestone fragments exhibiting subtle color variations in off-white cream and pale gray hues creating a light and natural palette that enhances authenticity. These larger limestone pieces are interspersed with smaller finer grains originating from mixed sedimentary materials resulting in a complex uneven surface with a natural distribution of particles. This combination forms a loose unbound gravel bed free from adhesives or binders showcasing realistic porosity and allowing weathering effects such as minor chips dust accumulation and faint discolorations from environmental exposure to be visible across the matte slightly rough surface finish.

The texture’s physical attributes are carefully captured through its PBR channels: the BaseColor (Albedo) channel accurately reflects the limestone’s natural tones and the subtle color shifts among the finer gravel grains delivering a nuanced granular appearance. The Normal map emphasizes the irregular uneven geometry of both the larger gravel fragments and the fine grains enhancing tactile depth and surface complexity. Its Roughness channel simulates the matte non-glossy finish typical of natural limestone and the gritty texture of the fine gravel while the Metallic channel remains near zero representing the non-metallic mineral composition authentically. Ambient Occlusion deepens the visual perception by accentuating shadows in crevices between particles and the Height (Displacement) map captures delicate elevation differences between larger gravel fragments and finer grains crucial for realistic parallax and tessellation effects in 3D engines.

This seamless texture is fully optimized and unreal blender ready designed for seamless integration within Blender Unreal Engine and Unity workflows. It guarantees no visible tiling artifacts even at close inspection due to its 8K resolution making it ideal for realistic landscape visualizations garden paths and natural ground covers where high fidelity is essential. For optimal results it is recommended to carefully adjust the UV scale to maintain natural size relationships between gravel particles and surrounding elements. Additionally fine-tuning the roughness channel can effectively simulate varying environmental conditions such as wet or dry gravel surfaces while blending height and normal maps enhances surface detail further elevating the realism of outdoor gravel beds 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.
