This seamless 3D texture presents coal chunks with a fractured surface rendered in stunning 8K resolution, capturing the intricate details of natural broken coal pieces. The material composition reflects the organic mineral base of coal, with irregular aggregates and rough, jagged edges that emphasize its coarse grain structure. The deep black color is true to authentic coal, resulting from natural carbon-rich pigments and subtle oxide layers that give the surface a slightly varied, matte finish. The texture exhibits visible fissures and cracks, indicative of weathered and fragmented coal, while porosity and surface roughness enhance realism by mimicking the unevenness found in raw coal chunks.

In PBR workflow terms, the BaseColor (Albedo) channel delivers the rich coal color deep black with subtle tonal variation, while the Normal map defines the fractured and coarse grain topography, creating realistic light interaction with the surface irregularities. The Roughness map highlights the texture’s naturally rough and weathered finish, avoiding any artificial glossiness. The Metallic channel remains near zero to reflect coal’s non-metallic nature. Ambient Occlusion enhances the depth of fissures and cracks, giving the material an authentic shadowing effect. Height and Displacement maps provide accurate surface relief, essential for close-up renders and parallax effects.

Designed for seamless tiling, this 8K texture is fully optimized and ready for use in Unreal Engine, Blender, and Unity, making it ideal for photorealistic 3D models requiring detailed coal surfaces. When applying this texture, adjusting the UV scale carefully is recommended to preserve the fine fractured details without visible repetition. Additionally, fine-tuning the roughness map can help achieve the perfect balance between matte and slightly reflective surfaces, enhancing the natural appearance of fragmented coal chunks under various lighting conditions.

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.
