The Seamless Coral Gravel texture by Texture Haven is a meticulously crafted PBR 3D material designed to authentically replicate the natural composition of coral gravel—a unique organic substrate formed from fragmented coral skeletons blended with fine mineral grains and sediments. This texture captures the intricate interplay of porous weathered surfaces typical of coastal gravel beds revealing subtle variations in grain size shape and orientation that contribute to its rugged yet cohesive appearance. The base substrate mainly consists of calcium carbonate from coral fragments bonded with finer mineral particles and sediments resulting in a durable surface with a naturally eroded finish. Its color palette features soft off-white and pale beige tones accented by muted orange and coral hues which emulate the natural pigment distribution and oxide layers commonly found in marine environments lending the texture a lifelike visual depth and organic charm.

In the PBR workflow the Base Color (Albedo) channel accurately conveys the delicate color transitions and mottled patterns characteristic of weathered coral gravel while the Normal map enhances the perception of depth by emphasizing the rough uneven surface detail of the aggregate. The Roughness map is finely tuned to reflect the semi-matte slightly porous finish of aged coral gravel allowing soft light scattering and realistic highlights that respond naturally across different lighting conditions. The Metallic channel remains minimal consistent with the non-metallic organic nature of the material. Ambient Occlusion adds subtle shadowing within crevices and between grains improving overall depth and realism while Height and Displacement maps provide additional surface geometry enabling physically accurate deformation for enhanced tactile authenticity in close-up renders.

Optimized for seamless tiling this texture pack ensures clean repetition with no visible seams making it ideal for large-scale outdoor terrains coastal environments or natural stone surfaces in high-fidelity 3D scenes. It is fully compatible with leading rendering engines such as Blender Unreal Engine and Unity supporting workflows that utilize the Principled BSDF shader or equivalent setups by feeding Base Color Roughness Normal and Ambient Occlusion maps into engine-specific material systems. With resolution options up to 8K it delivers exceptional detail suitable for detailed close-up shots and demanding visual projects. For best results it is recommended to adjust UV scaling thoughtfully to maintain consistent texel density and combine the Normal map with Height or Parallax Occlusion techniques to enhance perceived surface complexity and realism further.

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.
