This seamless 3D texture presents an 8K resolution photorealistic coal surface characterized by its dense, solid composition and smooth black color. The base substrate mimics natural coal’s organic mineral structure, with fine grain orientation and tightly packed carbon aggregates that contribute to its dense appearance. The surface finish is highly reflective and glossy, resembling a freshly polished, wet coal face with subtle shiny flakes dispersed throughout. These reflective flakes simulate embedded crystalline impurities and microfacets, adding depth and realism to the texture. The black coal color is achieved through deep pigment layers combined with oxide tinting, producing a rich, uniform dark tone that enhances the visual impact in 3D applications requiring authentic coal materials.
In terms of PBR channels, the BaseColor (Albedo) captures the smooth, saturated coal black with scattered shiny flakes highlighted by variations in tint and gloss. The Normal map accurately renders the fine grain and micro-relief of the surface, providing tactile detail without excessive roughness. The Roughness map maintains a low to medium range, emphasizing the polished, wet look while allowing subtle surface imperfections that prevent a plastic-like effect. The Metallic channel is minimal, reflecting coal’s organic and non-metallic nature, while Ambient Occlusion enhances the perception of depth in crevices and grain boundaries. Finally, the Height (Displacement) map offers gentle relief contrast, perfect for subtle parallax effects or displacement in engines like Unreal, Blender, or Unity.
This texture is optimized for seamless tiling, making it ideal for large-scale surfaces without visible repetition, and its 8K resolution ensures exceptional detail even in close-up renders. It is fully compatible and ready for use in popular 3D software including Blender, Unreal Engine, and Unity, enabling artists to achieve highly realistic coal surface materials efficiently. For practical use, adjusting the UV scale to moderate values helps maintain the balance between detail and performance, while fine-tuning the roughness map can enhance the wet glossy finish to suit different lighting environments. Height map adjustments can also be employed for subtle parallax effects to boost realism in interactive or real-time scenes.
The coal surface features shiny flakes and a smooth texture with a rich black color, creating an unreal Blender-ready material that accurately represents PBR characteristics.
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.
