This seamless 3D texture presents an ultra-high-definition 8K resolution portrayal of a glossy, wet coal surface in rich charcoal color, ideal for photorealistic rendering and visualization. The material is composed of densely packed organic coal particles with a smooth, solid substrate, enhanced by natural binders and subtle mineral impurities that create fine grain details and reflective shiny flakes. These flakes scatter light delicately across the surface, producing the characteristic wet and glossy appearance typical of freshly moistened coal. The texture mimics the natural porosity and compact grain orientation found in coal deposits, while the surface finish is polished with a slight sheen that accentuates the wet look without appearing overly reflective or plastic-like.
In terms of PBR channels, the BaseColor (Albedo) captures the deep charcoal tones with nuanced variations from dark gray to near-black, enriched by faint color shifts caused by organic pigments and mineral inclusions. The Normal map emphasizes the subtle surface imperfections and fine grain structure, delivering realistic depth and tactile roughness. The Roughness channel balances the glossy wetness by providing low roughness values where the shiny flakes catch light, contrasted with slightly higher roughness in matte areas to maintain natural variation. The Metallic channel is minimal or near zero, reflecting the non-metallic organic nature of coal, while the Ambient Occlusion map enhances shadowing in crevices and grain boundaries for added depth. Height and Displacement maps provide gentle elevation shifts that simulate the dense yet irregular coal surface, supporting more realistic parallax and bump effects in 3D engines.
This coal surface texture is fully optimized and ready for integration in Blender, Unreal Engine, or Unity pipelines, offering artists and developers a versatile material for projects requiring authentic coal visuals with wet and glossy characteristics. For best results, it is recommended to adjust the UV scale carefully to prevent tiling artifacts and to fine-tune the roughness slider to control the intensity of wetness reflections according to scene lighting. The high-resolution 8K detail ensures the texture holds up under close camera scrutiny, making it suitable for both real-time applications and high-end rendering scenarios. This PBR texture is an excellent choice for natural environment scenes, mining visualizations, industrial assets, or any project demanding a realistic, seamless coal surface with shiny wet qualities.
The coal material features a charcoal color with a glossy, wet surface that highlights shiny flakes, creating a realistic and unreal Blender-ready PBR texture.
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.
