This seamless 8K 3D PBR texture showcases a coal surface characterized by its deep black color and densely packed reflective flakes, creating a visually rich and natural appearance. The base material simulates the organic mineral structure of coal, combining fine grain aggregates with a solid, compact substrate. This composition results in a smooth yet textured surface that mimics real coal’s glossy, wet finish, enhanced by subtle variations in reflectivity and a natural wet sheen. The shiny flakes embedded within the surface simulate the crystalline inclusions and mineral impurities typical of authentic coal, providing a striking interplay of light and shadow across the texture.
The texture’s PBR channels are carefully crafted to replicate these material properties for photorealistic rendering. The BaseColor (Albedo) channel features a consistent deep black tone with nuanced dark gray highlights representing the coal’s natural pigmentation and subtle mineral veins. The Normal map captures the fine grain details and slight surface irregularities, giving depth and tactile realism to the smooth yet uneven surface. Roughness is calibrated to deliver a predominantly glossy finish with localized variations around the reflective flakes, enhancing the wet, polished appearance. The Metallic channel is minimal, reflecting coal’s non-metallic nature, while Ambient Occlusion emphasizes the dense, compact form with soft shadows in crevices. Height/Displacement maps simulate minor surface undulations and flake relief, adding further depth when used with parallax or tessellation techniques.
Designed at an ultra-high 8K resolution, this texture is optimized for demanding 3D projects in Blender, Unreal Engine, and Unity, ensuring crisp detail even on close-up surfaces. Its seamless nature allows for flexible UV mapping without visible tiling, making it ideal for large-scale models or environments requiring consistent coal surfaces. For best results, adjusting the roughness slightly downward can increase the wet shine effect, while fine-tuning the UV scale helps maintain realistic flake size and distribution. Incorporating height or parallax occlusion mapping is recommended to elevate surface depth and enhance realism in interactive or cinematic scenes.
The 3D texture features a coal color deep black base with coal surface shiny flakes that create a coal surface reflective effect, making it an unreal Blender ready material for realistic rendering.
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.
