The Gravel Coral seamless 3D texture is a physically based rendering (PBR) material designed to replicate the natural composition and appearance of coral gravel found along coastal terrains. This texture features a detailed base substrate composed primarily of weathered mineral aggregates with fine organic fragments typical of coral formations. These particles are bound together by subtle variations in natural cementation processes resulting in a porous uneven surface with characteristic roughness and intricate grain orientation. The surface finish captures the naturally matte slightly eroded quality of coral stones exposed to outdoor elements with soft color variations from warm beige to pale coral hues enhanced by subtle oxide layers and pigments that appear distinctly in the Albedo/BaseColor channel. The Normal map effectively conveys the micro-geometry of the rough stone surfaces and ground grit while the Roughness map balances the tactile feel of both polished and weathered sections simulating realistic light scattering and reflections typical of coastal rock and gravel environments.

Included in this PBR set are high-resolution 4K textures with an optional 8K upgrade offering exceptional detail for high-end workflows in Blender Unreal Engine and Unity. The material’s Height and Ambient Occlusion maps contribute to accurate displacement and subtle shadowing effects further enhancing depth and realism for outdoor terrain or natural ground surfaces. The texture is fully tileable allowing seamless repetition without visible borders making it optimal for use in large-scale terrain projects or detailed environment assets. The metallic channel is deliberately kept minimal to reflect the non-metallic nature of natural coral gravel ensuring physically accurate shading in both real-time and offline renderers. This texture has been calibrated for consistent results across various digital content creation software and game engines supporting the metal-rough workflow commonly used in modern PBR pipelines.

For optimal application it is recommended to adjust the UV scale to match the intended environment scale as coral gravel displays distinct granularity that can be lost if scaled improperly. Additionally fine-tuning the roughness map can enhance the interplay of light on the surface especially in outdoor lighting conditions where wet or dry effects might be simulated. Leveraging the Height map for subtle parallax effects can further increase the perceived depth of the texture on terrain meshes giving a more immersive and natural appearance to coastal ground and rocky landscapes.

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.
