This seamless 3D PBR texture in stunning 8K resolution showcases the natural surface of lignite coal, renowned for its matte, dry appearance and distinctive dark gray color. The base substrate consists of compacted organic mineral matter typical of lignite, exhibiting fine grain orientation and porous microstructure that conveys a realistic weathered coal deposit. Dusty residue and subtle dust accumulation on the rough, raw surface enhance the authenticity, while the texture’s fine details capture the intricate microstructure of coal particles bound by natural organic adhesives. These characteristics give the coal surface a distinctly matte finish, avoiding shine or gloss, and emphasizing its dry, natural state suitable for photorealistic renderings.
In the PBR workflow, the BaseColor or Albedo channel accurately represents the coal’s deep dark gray hues with subtle variations due to dust and residue. The Normal map highlights the rough, porous surface structure and grain details, providing convincing depth and tactile complexity. Roughness values are high to maintain the matte quality, preventing unwanted reflections, while the Metallic channel remains near zero to reflect the coal’s non-metallic nature. Ambient Occlusion enhances shadowed crevices within the compacted coal matrix, and the Height/Displacement map captures the surface irregularities and fine grains, adding realism through parallax effects. This texture is optimized for seamless tiling, ensuring smooth repetition without visible seams or distortions, making it ideal for large-scale coal surface visualizations.
Designed for compatibility with major 3D engines like Unreal Engine, Blender, and Unity, this lignite coal texture is ready to integrate into realistic natural environments, mining scenes, or geological visualizations requiring authentic coal surfaces. For best results, adjusting UV scale to match the model’s physical dimensions will preserve the fine grain and dusty details, while tweaking roughness can help balance the matte finish under different lighting conditions. This texture offers a versatile and highly detailed solution for artists and developers aiming to achieve photorealistic, natural coal renderings with ease and precision at ultra-high 8K resolution.
This 3D texture features a coal surface matte finish with a coal color dark gray tone, optimized for Unreal and Blender ready PBR workflows to ensure realistic material composition and appearance.
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)
- Enable the addon: Edit → Preferences → Add-ons → Node Wrangler.
- Create a material and select the Principled BSDF node.
- 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.
- Add AO and Height using the “Manual wiring” steps below (5 and 6).
Manual wiring (full control)
- Create a material (Material Properties → New) and open the Shader Editor.
- Add an Image Texture node for each map. Set Color Space:
- Albedo → sRGB
- AO, Roughness, Metallic, Normal, Height, ORM → Non-Color
- Connect to Principled BSDF:
albedo → Base Colorroughness → Roughnessmetallic → Metallic (for wood this often stays near 0)normal → Normal Map node (Type: Tangent Space) → Normal of Principled.
If details look “inverted”, enable Invert Y on the Normal Map node.
- 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).
- Height / Displacement:
Cycles — true displacement
- Material Properties → Settings → Displacement: Displacement and Bump.
- Add a Displacement node: connect
height → Height, set Midlevel = 0.5, Scale = 0.02–0.08 (tune to taste).
- Output of Displacement → Material Output → Displacement.
- Add geometry density (e.g., Subdivision Surface) so displacement has polygons to work with.
Eevee (or lightweight Cycles) — bump only
- Add a Bump node:
height → Height.
- 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:
- Add one Image Texture (Non-Color) → Separate RGB (or Separate Color).
- R (red) → AO (use it in the Multiply node with albedo as above).
- G (green) → Roughness of Principled.
- B (blue) → Metallic of Principled.
UVs & seamless tiling
- These textures are seamless. If your mesh has no UVs, go to UV Editing → Smart UV Project.
- 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.
