This seamless 8K PBR 3D texture presents a photorealistic surface of coal nuggets embedded in a dense, solid black substrate, characterized by shiny, reflective flakes scattered across its smooth, glossy finish. The base material mimics natural coal, an organic mineral composed primarily of carbon with fine grain structures and occasional mineral inclusions that create subtle variations in reflectivity and color depth. The surface appears wet and polished, enhancing its reflective qualities and emphasizing the intricate details of the coal’s granular composition. This texture captures the coal’s unique interplay between matte black areas and sparkling shiny flakes, offering a natural and dynamic visual effect that is ideal for realistic 3D rendering and visualization projects requiring a coal surface shiny flakes look with high fidelity.
In terms of PBR material channels, the BaseColor (Albedo) map reproduces the deep black tones of coal interspersed with lighter, reflective flakes that add visual complexity. The Normal map defines the fine grain orientation and subtle surface irregularities typical of coal nuggets, contributing to a tactile, three-dimensional feel. The Roughness channel varies across the surface, with lower roughness values on the shiny flake areas to reflect light sharply, while the surrounding coal matrix remains slightly more diffuse. The Metallic map is minimal or absent, reflecting coal’s non-metallic nature, whereas Ambient Occlusion enhances the perception of depth between nuggets and crevices. The Height or Displacement map captures the uneven topography of coal nuggets, giving additional realism in close-up views and parallax effects.
Rendered at an impressive 8K resolution, this texture is optimized for use in major 3D engines such as Blender, Unreal Engine, and Unity, ensuring crisp, detailed visuals even on large-scale surfaces. Its seamless design allows for easy tiling without visible borders, making it suitable for extensive environments or high-detail models. For optimal results, adjusting the UV scale to maintain the natural size of coal nuggets is recommended, along with fine-tuning roughness settings to balance the wet, glossy appearance with subtle matte areas for enhanced realism. This texture is particularly useful for projects requiring authentic coal surfaces with shiny reflective qualities, from industrial visualizations to game environments and realistic material studies.
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.
