This seamless 3D PBR texture at 8K resolution meticulously captures the essence of crystal onyx, showcasing its complex crystalline structure and distinctive translucent layers. The base material is a natural onyx stone, characterized by a fine-grained calcite substrate interspersed with mineral veins that provide unique patterns and depth. These veins, formed through mineral impurities, create an organic veined pattern that is irregular yet harmonious, contributing to the stone's signature appearance. The texture’s geometric form is predominantly veined and laminated, reflecting the layered sedimentary growth of onyx, with smooth transitions between its translucent strata that simulate light passing through the stone.

At the material composition level, the onyx substrate is bound by natural mineral cements that hold the crystalline aggregates together, resulting in a solid, low-porosity surface. This contributes to the texture’s minimal weathering effects and its characteristic polished finish. The polished surface enhances the onyx’s natural shine and reflective properties, which are accurately represented in the PBR maps. The BaseColor (Albedo) channel captures the subtle color gradations from creamy whites to warm ambers, while the Normal and Height maps emphasize the delicate undulations of the crystalline formations and mineral veins. The Roughness map reflects the smooth, almost glass-like finish of polished onyx, with low roughness values to simulate its reflective surface. Metallic values remain near zero, consistent with onyx’s non-metallic nature, while Ambient Occlusion enhances the perception of depth within the stone’s intricate layers.

Designed for high-fidelity 3D rendering, this texture is optimized for use in Blender, Unreal Engine, and Unity, ensuring compatibility with the latest rendering pipelines. The 8K resolution provides exceptional detail, allowing for close-up visualizations without loss of quality, which is ideal for architectural visualizations, luxury interior designs, and natural stone applications. The translucent layers are rendered with subtle variations in opacity, contributing to a realistic depth effect, which can be further enhanced by blending the Height and Normal maps to simulate parallax and micro-surface detail.

For practical application, it is recommended to carefully adjust the UV scale to balance detail and performance, especially when used in large surface areas. Additionally, fine-tuning the roughness values allows for control over the onyx’s polished finish, enabling variations from a high-gloss reflective surface to a softly diffused sheen. Combining height map displacement with normal mapping can amplify the tactile realism of the crystalline structure, providing a convincing illusion of depth and texture without excessive geometry complexity.

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.
