This seamless 3D PBR 8K texture captures the intricate beauty of marbled onyx, a natural stone distinguished by its smooth mineral veins and distinctive color shifts. Onyx is primarily composed of calcite or aragonite, crystalline forms of calcium carbonate, which create the translucent substrate. The texture's base material reveals a polished surface that accentuates its glossy finish and natural shine, allowing subtle tonal variations to emerge across the stone. These tonal shifts arise from variations in mineral content and light refraction within the semi-translucent layers, producing a rich depth and complexity in the BaseColor (Albedo) channel.

The geometric form of this texture is characterized by flowing, veined patterns that interlace across the surface, mimicking the natural layering and banding typical of onyx formations. The veins, depicted as smooth and polished, are rendered with high fidelity in the Normal and Height maps, emphasizing their gentle undulations and slight elevation differences. The texture exhibits low porosity, consistent with onyx's dense crystalline structure, which contributes to its reflective and glossy surface finish. This smoothness is conveyed in the Roughness map through predominantly low roughness values, enhancing the polished appearance while still allowing subtle micro-surface imperfections to simulate realistic light scattering.

The PBR workflow is carefully constructed to replicate the physical properties of onyx. The BaseColor channel reflects the warm, creamy hues and the striking onyx color shift, transitioning naturally between subtle whites, beiges, and amber tones. The Normal and Height maps work in tandem to capture the smooth veins and soft transitions in surface depth, while the Ambient Occlusion map adds shadowing to the recessed mineral veins, increasing visual depth. Metallic values remain near zero, as onyx is a non-metallic stone. The texture’s displacement data is finely tuned to allow for subtle parallax effects without exaggerating the flat polished surface, maintaining realism in close-up renders.

Engineered at an ultra-high 8K resolution, this texture is optimized for seamless tiling, ensuring that the marbled onyx pattern repeats without visible seams or distortions. It is fully compatible with Blender, Unreal Engine, and Unity, providing artists and developers with a versatile asset for photorealistic surface renderings, architectural visualizations, and luxury material applications. For practical use, adjusting the UV scale to maintain natural vein proportions is recommended, alongside fine-tuning the roughness channel to balance between gloss and diffuse reflection, depending on lighting conditions. Combining height and normal maps carefully can enhance the perception of depth while preserving the polished smoothness distinctive to 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.
