This seamless 3D PBR 8K texture captures the intricate details of layered onyx, a sedimentary stone characterized by its coarse grain and distinct mineral veins. The material’s natural pattern emerges from successive deposits of calcium carbonate, forming translucent bands interspersed with rougher, opaque layers. These sedimentary strata create a laminated geometric form, emphasizing the stone’s raw, earthy tones that range from warm creams to deep ambers and subtle browns. The rough texture and visible mineral veins give the surface an organic, unrefined appearance, faithfully replicating onyx’s naturally occurring coarse grain and layered composition.

The substrate of this onyx texture is primarily crystalline calcite, bound together in compact layers by natural cementation processes. The mineral veins consist of fine aggregates embedded within the stone matrix, adding depth and complexity to the surface. Porosity is minimal, reflecting the dense, solid nature of onyx, yet subtle weathering effects are simulated through variations in roughness and height maps. The surface finish mimics a raw, unpolished state, preserving the tactile unevenness and matte quality typical of rough onyx stone rather than a glossy or highly polished look.

Mapped to PBR channels, the BaseColor (Albedo) displays the earthy tones and mineral vein coloration, providing the foundational visual richness. The Normal map encodes the coarse grain and layered stratification, delivering realistic surface relief and depth when lit. Roughness values vary across the texture, with higher roughness on the raw, unpolished areas and slightly smoother transitions along the mineral veins, while the Metallic channel remains near zero, consistent with the non-metallic nature of onyx. Ambient Occlusion enhances the perception of depth within crevices and vein intersections, and the Height/Displacement map accentuates the layered sedimentary formation, supporting parallax or tessellation techniques in 3D applications.

Designed for high-fidelity rendering workflows, this texture is fully compatible with Blender, Unreal Engine, and Unity, ensuring seamless integration into diverse 3D environments. The 8K resolution guarantees exceptional detail even when viewed up close, making it suitable for architectural visualization, game environments, and realistic material studies. For practical use, it is recommended to adjust the UV scale carefully to maintain the natural size of the onyx layers and to fine-tune roughness maps to balance between the raw surface feel and subtle light diffusion. Additionally, blending height and normal maps can enhance the perception of depth without introducing excessive geometric complexity, optimizing performance while preserving visual authenticity.

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)

  1. Enable the addon: Edit → Preferences → Add-ons → Node Wrangler.
  2. Create a material and select the Principled BSDF node.
  3. 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.
  4. Add AO and Height using the “Manual wiring” steps below (5 and 6).

Manual wiring (full control)

  1. Create a material (Material Properties → New) and open the Shader Editor.
  2. Add an Image Texture node for each map. Set Color Space:
    • AlbedosRGB
    • AO, Roughness, Metallic, Normal, Height, ORMNon-Color
  3. Connect to Principled BSDF:
    • albedoBase Color
    • roughnessRoughness
    • metallicMetallic (for wood this often stays near 0)
    • normalNormal Map node (Type: Tangent Space) → Normal of Principled. If details look “inverted”, enable Invert Y on the Normal Map node.
  4. 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).
  5. Height / Displacement:
    Cycles — true displacement
    1. Material Properties → SettingsDisplacement: Displacement and Bump.
    2. Add a Displacement node: connect heightHeight, set Midlevel = 0.5, Scale = 0.02–0.08 (tune to taste).
    3. Output of Displacement → Material Output → Displacement.
    4. Add geometry density (e.g., Subdivision Surface) so displacement has polygons to work with.
    Eevee (or lightweight Cycles) — bump only
    1. Add a Bump node: heightHeight.
    2. 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:

  1. Add one Image Texture (Non-Color) → Separate RGB (or Separate Color).
  2. R (red) → AO (use it in the Multiply node with albedo as above).
  3. G (green) → Roughness of Principled.
  4. B (blue) → Metallic of Principled.

UVs & seamless tiling

  1. These textures are seamless. If your mesh has no UVs, go to UV EditingSmart UV Project.
  2. 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.
