The Coral Ground — Gravel Debris Sandy Ground Costal Stones texture is a meticulously crafted seamless 3D texture designed to replicate a natural coastal environment with high fidelity. Its base substrate is an organic-mineral blend capturing the intricate composition of coral fragments porous stones and sandy gravel commonly found along ocean shorelines and exposed seabeds. The material’s surface exhibits a naturally weathered finish reflecting the effects of erosion and sediment accumulation over time. Subtle color variations arise from natural pigments and oxide layers creating a realistic palette of off-whites sandy beiges and muted coral tones. This porous surface texture features fine grain orientation that enhances the tactile depth while binders and natural cementation are implied through the rough yet stable cohesion of debris and stones all of which contribute to the authentic look and feel of reef and coastline terrain. The texture’s PBR channels are carefully calibrated to reflect these material qualities: the Albedo (BaseColor) map conveys the nuanced coloration of coral and sand; the Normal map details the uneven granular surface and stone relief; the Roughness map captures the varying matte and slightly glossy patches caused by wet and dry areas; the Height map enables realistic depth and displacement effects that emphasize the coral ground’s uneven topography; the Ambient Occlusion map enhances shadowing in crevices and beneath debris; and the Metallic channel remains minimal to maintain the natural non-metallic character of the substrate.

This seamless 3D texture is provided at a native 4K resolution with an optional 8K upgrade for high-end projects requiring exceptional detail. It is optimized for modern pipelines and is fully compatible with Blender Unreal Engine and Unity ensuring reliable and consistent shading across real-time and offline renderers. The texture supports the metal/rough workflow making it easy to integrate without manual tweaking and balances fine detail with performance to suit outdoor terrain reef environments and natural coastline scenes. Its tileable nature allows for extensive coverage without visible repetition making it ideal for simulating broad areas of sandy gravel coral debris and rocky ground. For best results adjusting the UV scale to match the intended scene scale and fine-tuning roughness values can enhance the realism of wet versus dry surfaces while subtle height map parallax can add convincing depth to exposed seabed and reef formations.

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.
