This seamless 3D PBR 8K texture captures the intricate composition of onyx chips embedded within a rough, natural substrate. The base material consists primarily of calcite and quartz minerals, forming a sedimentary stone with characteristic coarse grains and mineral veins. The texture reveals a complex pattern of interlocking onyx fragments, exhibiting natural sedimentary layering that highlights the stone’s earthy color palette—ranging from warm beige and amber tones to deeper browns and subtle hints of gray. The rough surface finish reflects the raw, unpolished state of onyx, where natural weathering and slight porosity contribute to the tactile, uneven form. This coarse grain structure is emphasized in the Normal and Height maps, enhancing depth perception and surface irregularities in 3D applications.

From a materials perspective, the texture simulates the intricate layering and adhesive minerals binding the onyx chips together. The substrate acts as a cementing matrix, holding the fragmented grains in place, while the mineral veins introduce subtle variations in reflectivity and color. The BaseColor (Albedo) map accurately reproduces the natural pigments and earthy tones inherent to onyx, while the Roughness map defines the uneven, matte qualities of the raw surface—avoiding overly polished or metallic appearances. The Metallic channel remains minimal, reflecting the stone’s non-metallic nature, whereas the Ambient Occlusion map enhances shadowing within crevices and around the chip edges, adding realism to the sedimentary pattern.

The Height (Displacement) map provides fine-scale elevation differences, crucial for rendering the coarse grain texture and subtle relief of the natural onyx surface. These variations can be blended with Normal maps to achieve a more immersive material response under different lighting conditions. This texture’s resolution at 8K ensures exceptional detail, suitable for close-up renders in Blender, Unreal Engine, and Unity, supporting high-fidelity architectural visualizations and naturalistic 3D environments. The seamless tiling feature allows for extensive coverage without visible repetition, maintaining the organic, random appearance characteristic of onyx stone.

For practical use, it is recommended to carefully adjust the UV scale to match the intended physical size of onyx chips, as improper scaling can distort the natural pattern and grain detail. Additionally, fine-tuning the Roughness map can help balance the interplay between matte and slightly reflective areas, enhancing realism depending on the lighting setup. When using displacement or parallax mapping, blending these with Normal maps will provide a more nuanced surface form, capturing both macro and micro details of the onyx roughness and sedimentary structure.

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.
