This seamless 3D texture presents a highly detailed photorealistic representation of polished black onyx, rendered at an impressive 8K resolution to capture every nuance of the material’s natural complexity. Black onyx is a fine-grained, cryptocrystalline variety of quartz, composed primarily of silicon dioxide, exhibiting a smooth, glossy surface that results from meticulous polishing. The texture reveals an intricate pattern of onyx veins—thin, irregular mineral inclusions and crystalline banding—that traverse the slab, creating dynamic visual depth and organic flow. These veins are embedded within a dark, nearly opaque black substrate, whose slight translucency and subtle tonal variations reflect the natural crystal structure of onyx, characterized by alternating layers of chalcedony and quartz that give rise to its distinctive veined appearance.

Structurally, the texture simulates a polished slab form, where the base material’s mineral grains are tightly compacted with no visible porosity, indicative of a dense and durable stone. The absence of surface imperfections emphasizes the refined finish, where the surface finish is highly reflective and smooth to the touch. This polished sheen is faithfully recreated through the roughness map, which features very low roughness values to simulate the glossy luster seen in real black onyx slabs. The normal and height maps highlight the subtle undulations and fine veins, adding realistic depth and three-dimensionality to the material. Ambient occlusion enhances the perception of crevices and vein boundaries, while the metallic channel remains minimal, reflecting the stone’s non-metallic mineral composition.

The base color (albedo) channel captures the deep black tones interspersed with lighter veins, reproducing the natural pigment variations caused by trace mineral impurities and the crystalline layering inherent in onyx. This high-resolution texture is optimized for seamless tiling, ensuring that when applied across large surfaces, the veined pattern flows continuously without visible seams or repetition artifacts. Its preparation includes careful calibration of UV scale to maintain natural vein proportions in 3D environments. This texture is compatible with leading rendering and game engines such as Blender, Unreal Engine, and Unity, supporting PBR workflows that fully leverage the detailed maps for photorealistic results.

When working with this black onyx texture, it is advisable to fine-tune the roughness parameter to balance glossiness based on environmental lighting conditions, as overly low roughness may cause excessive reflections in darker scenes. Additionally, blending the height map with normal maps can enhance surface detail without harsh displacement artifacts, especially useful in real-time engines where performance is a consideration. This attention to material and form details makes the texture particularly suitable for luxury interiors, architectural visualizations, or high-end product design where the natural elegance and depth of polished onyx slabs are desired.

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.
