This seamless 3D PBR texture in stunning 8K resolution showcases a cracked dry coal surface characterized by a deep black coal color that captures the natural essence of weathered mineral deposits. The base substrate reflects an organic carbonaceous material typical of coal, featuring rough coarse grains and fissures that form through natural drying and environmental exposure. These cracks and porous details are accentuated by dusty residue and subtle variations in surface finish, simulating the interplay of light and shadow on uneven, matte surfaces. The texture’s composition highlights the brittle, fractured nature of coal with realistic grain orientation and natural weathering effects, providing a highly authentic portrayal of dry coal surfaces that are far from uniform or polished.
Within the PBR workflow, this texture excels across multiple channels to enhance photorealistic rendering and accurate material representation. The BaseColor (Albedo) channel reveals the deep black coal coloration with subtle tonal shifts to emphasize natural variation. The Normal map captures the intricate fissures and coarse grain relief, adding depth and tactile roughness. Roughness values are carefully balanced to reflect a predominantly matte, dusty surface with occasional smoother patches where finer dust has settled. The Metallic channel remains near zero, consistent with coal’s non-metallic nature, while Ambient Occlusion enhances shadowing within cracks and crevices, lending additional realism. The Height (Displacement) map provides precise elevation data, enabling detailed parallax effects and enhancing the perception of cracked depth for advanced 3D applications.
Engineered for versatility, this high-resolution 8K PBR texture is fully optimized and ready for integration into Blender, Unreal Engine, and Unity projects. Its seamless design ensures effortless tiling across large surfaces without visible repetition, making it ideal for large-scale environmental scenes or close-up object details. For practical use, adjusting the UV scale is recommended to maintain natural grain proportions, and fine-tuning roughness parameters can help achieve the desired balance between dusty matte and slightly reflective coal surfaces. Leveraging the height map with parallax occlusion mapping will notably enhance realism in interactive or cinematic renderings, capturing the complex surface geometry of cracked dry coal in a way that standard textures cannot replicate.
The coal surface cracked texture features a dry, deep black coal color with detailed 3D texture elements, creating a realistic yet unreal Blender-ready PBR material.
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.
