This seamless 3D PBR 8K texture represents a meticulously crafted agate onyx surface, distinguished by its fine grain structure and polished glossy finish. The base material is natural onyx, a form of chalcedony composed primarily of silica, exhibiting characteristic smooth mineral veins and subtle banding patterns. The texture captures the stone’s unique geological formation, where fine agate inclusions create delicate, translucent layers that contribute to the depth and complexity of the material. This veined pattern is irregular yet harmonious, replicating the organic variations found in authentic onyx slabs.

The substrate appears dense and homogenous, with minimal porosity, reflecting the compact crystalline structure of onyx. The polished surface finish is achieved through a high-gloss refinement process, producing a reflective sheen that highlights the stone’s inherent natural shine and enhances its visual depth. This finish is critical in the texture’s Roughness map, where low roughness values create a smooth, mirror-like surface, while subtle variations correspond to microscopic surface imperfections. The Normal and Height maps emphasize the fine grain and gentle undulations of the mineral veins, adding tactile realism and dimensionality to the material’s form.

Coloration in this texture is derived from natural pigments embedded within the mineral veins—ranging from creamy whites to soft browns and occasional hints of amber—mimicking the subtle chromatic shifts caused by mineral impurities. The BaseColor (Albedo) map accurately reproduces these nuanced hues without artificial saturation, maintaining the stone’s authentic appearance. The Ambient Occlusion map enhances the perception of depth within the veined patterns by simulating soft shadowing in crevices and grain transitions. Metallic values remain near zero, consistent with the non-metallic nature of onyx.

Designed for seamless tiling, this texture is optimized at 8K resolution, ensuring exceptional detail and clarity for high-end rendering in Blender, Unreal Engine, and Unity. The flawless repeatability makes it suitable for extensive surfaces such as flooring, wall cladding, or decorative panels without visible seams. For practical use, it is recommended to carefully adjust the UV scale to maintain realistic vein proportions relative to the model’s dimensions. Additionally, fine-tuning the Roughness map can enhance the balance between glossiness and subtle surface wear, and blending the Normal and Height maps can improve depth perception for close-up views or parallax effects.

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.
