This seamless 3D PBR 8K texture captures the intricate beauty of banded onyx, a natural stone renowned for its layered mineral formations and smooth veining. The material is characterized by parallel bands of translucent and opaque layers, creating a striking tonal variation that ranges from creamy whites and warm beiges to deep amber and rich browns. These layers represent the geological deposition of calcite and quartz, forming a crystalline structure that provides subtle depth and complexity to the surface. The texture’s form is essentially veined and laminated, highlighting the natural stratification and mineral veins typical of onyx, with smooth transitions between bands that emphasize its organic origin.

The substrate of this texture mimics the dense calcite base of onyx, exhibiting low porosity and a naturally compact grain structure. The mineral veins appear as embedded aggregates within the calcite matrix, giving rise to the distinctive smooth veins and occasional crystal inclusions. The polished glossy finish replicates a high-quality honed surface treatment, achieved in real materials by precision grinding and polishing to reveal the stone’s translucency and enhance its reflective properties. This finish is essential in capturing the natural sheen and reflective surface typical of premium onyx slabs, contributing to the texture’s low roughness values and subtle specular highlights.

In terms of PBR workflow, the BaseColor (Albedo) channel showcases the rich tonal variation and natural patterning without baked lighting, preserving color accuracy. The Normal map encodes the fine surface detail of smooth veins and subtle undulations within the crystalline structure, enhancing light interaction. Roughness is kept low and consistent to simulate the polished finish, ensuring sharp reflections and a glossy appearance. The Metallic channel remains at zero, as onyx is a non-metallic mineral. Ambient Occlusion subtly reinforces the layered depth and vein recesses, while the Height/Displacement map accentuates the gentle relief of banding and mineral veins for realistic parallax and shadowing effects.

This texture is optimized for high-end rendering engines including Blender, Unreal Engine, and Unity, supporting seamless tiling without visible repetition or seams at 8K resolution. Such detail enables close-up inspection and photorealistic material creation in architectural visualization, interior design, and product rendering. For practical use, it is recommended to carefully adjust the UV scale to maintain natural band proportions and to fine-tune roughness to balance glossiness according to lighting conditions. Additionally, blending the Height and Normal maps can enhance surface realism when simulating the subtle depth variations inherent in polished onyx surfaces.

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.
