This seamless 3D PBR 8K texture faithfully represents onyx stone characterized by distinctive striations and a rough, natural surface. Onyx, a sedimentary form of chalcedony, exhibits layered mineral veins and coarse grain formations that create an organic, raw appearance. The texture’s base material mimics this geological substrate, with alternating bands of translucent and opaque layers, capturing the mineral’s laminated structure. These striations reflect the slow deposition of silica-rich solutions, resulting in a natural pattern that balances smooth and coarse elements, conveying the stone’s earthy tones from deep browns to muted creams.

The material composition is detailed through a complex interplay of micro-aggregates and mineral inclusions, which contribute to the texture’s subtle porosity and slight weathering effects. The surface finish is intentionally rough and unpolished, emphasizing the natural rawness of onyx rather than a glossy or polished sheen. This roughness translates into the PBR roughness channel, providing realistic light scattering and matte reflections. The normal and height maps expertly capture the fine undulations and sedimentary layering, adding depth and tactile variation. Ambient occlusion enhances the perception of crevices and mineral veins, while the metallic channel remains near zero, reflecting onyx’s non-metallic, earthy nature.

Color information is embedded in the BaseColor (Albedo) map, showcasing the stone’s warm, earthy palette with subtle gradient shifts and mineral vein highlights. The texture’s fine detail and high resolution at 8K ensure exceptional clarity and realism, making it suitable for high-end rendering workflows. It is optimized for seamless tiling, allowing for continuous surfaces without visible repetition. This makes the texture highly compatible with major 3D engines such as Blender, Unreal Engine, and Unity, supporting physically based rendering pipelines and facilitating realistic material setups.

When applying this texture, it is advisable to adjust the UV scale to maintain the natural size and spacing of the onyx striations, avoiding distortion that could break the continuity of the sedimentary layers. Additionally, fine-tuning roughness values can help simulate varying weathering conditions, from freshly quarried stone to lightly eroded surfaces. For enhanced realism, blending the height map with parallax or normal maps can produce convincing depth effects, especially on large-scale architectural or environmental models where tactile surface detail is critical.

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.
