This seamless 8K 3D PBR texture showcases a highly detailed coal surface characterized by layered sedimentary formations in a deep dark gray color. The base material reflects a natural organic substrate composed of compacted carbon-rich mineral layers, tightly bound by natural adhesives formed through geological processes. The surface exhibits coarse grains interspersed with dusty residue and subtle fissures that reveal the stratified nature of sedimentary coal. Porosity is low but visible in micro-cracks and weathered areas, contributing to a dry, matte finish with naturally roughened texture. The dark gray coal color is rich and true to life, enhanced by subtle oxide layers and mineral inclusions that add depth and visual complexity to the surface appearance. This combination of mineral sediment, organic binders, and layered grain orientation creates an authentic and tactile coal surface ideal for photorealistic 3D rendering and modeling projects where realistic sedimentary coal textures are required.
In the PBR workflow, the BaseColor/Albedo channel captures the coal’s dark gray pigmentation mixed with dusty, muted highlights that emphasize the sediment layers. The Normal map accurately represents the fissured surface details and the coarse grain structure, adding realistic depth and shadow interplay. Roughness values range from medium to high, reflecting the dry, non-reflective finish typical of coal, while the Metallic channel remains near zero, as coal is non-metallic. Ambient Occlusion enhances the crevices and fissures, reinforcing the stratified look, and the Height/Displacement map conveys the subtle elevation shifts of the layered sediment, perfect for parallax or tessellation effects. This texture is optimized at a massive 8K resolution, ensuring exceptional clarity and detail for close-up renders.
Designed for compatibility with Unreal Engine, Blender, and Unity, this coal surface layered sediment texture is ready for seamless integration into any physically based rendering pipeline. For optimal results, it is recommended to carefully adjust the UV scale to preserve fine grain details and to fine-tune roughness settings depending on lighting conditions to enhance realism. The height map can also be leveraged for advanced parallax effects to simulate the subtle depth variations of the fissured coal surface, adding an extra layer of immersion to your materials. This texture is ideal for architects, game developers, and visual effects artists seeking a natural, stratified coal surface with realistic fissures and coarse sediment detail at the highest resolution available.
The 3d texture features a coal color dark gray with a coal surface fissured pattern, designed to be unreal blender ready for accurate PBR material representation.
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.
