This seamless 3D PBR 8K texture captures the intricate details of layered onyx, a sedimentary stone characterized by its coarse grain and distinct mineral veins. The material’s natural pattern emerges from successive deposits of calcium carbonate, forming translucent bands interspersed with rougher, opaque layers. These sedimentary strata create a laminated geometric form, emphasizing the stone’s raw, earthy tones that range from warm creams to deep ambers and subtle browns. The rough texture and visible mineral veins give the surface an organic, unrefined appearance, faithfully replicating onyx’s naturally occurring coarse grain and layered composition.
The substrate of this onyx texture is primarily crystalline calcite, bound together in compact layers by natural cementation processes. The mineral veins consist of fine aggregates embedded within the stone matrix, adding depth and complexity to the surface. Porosity is minimal, reflecting the dense, solid nature of onyx, yet subtle weathering effects are simulated through variations in roughness and height maps. The surface finish mimics a raw, unpolished state, preserving the tactile unevenness and matte quality typical of rough onyx stone rather than a glossy or highly polished look.
Mapped to PBR channels, the BaseColor (Albedo) displays the earthy tones and mineral vein coloration, providing the foundational visual richness. The Normal map encodes the coarse grain and layered stratification, delivering realistic surface relief and depth when lit. Roughness values vary across the texture, with higher roughness on the raw, unpolished areas and slightly smoother transitions along the mineral veins, while the Metallic channel remains near zero, consistent with the non-metallic nature of onyx. Ambient Occlusion enhances the perception of depth within crevices and vein intersections, and the Height/Displacement map accentuates the layered sedimentary formation, supporting parallax or tessellation techniques in 3D applications.
Designed for high-fidelity rendering workflows, this texture is fully compatible with Blender, Unreal Engine, and Unity, ensuring seamless integration into diverse 3D environments. The 8K resolution guarantees exceptional detail even when viewed up close, making it suitable for architectural visualization, game environments, and realistic material studies. For practical use, it is recommended to adjust the UV scale carefully to maintain the natural size of the onyx layers and to fine-tune roughness maps to balance between the raw surface feel and subtle light diffusion. Additionally, blending height and normal maps can enhance the perception of depth without introducing excessive geometric complexity, optimizing performance while preserving visual authenticity.
Using This PBR Texture in Blender
Import the texture maps into Blender with sRGB color space for albedo/base color and
Non-Color for normal, roughness, metallic, AO, height, and ORM maps. Connect normal maps
through a Normal Map node, then adjust UV scale with a Mapping node so the material repeats naturally on
your model.
- Albedo -> Principled BSDF Base Color
- Roughness -> Roughness, Metallic -> Metallic
- Normal -> Normal Map node -> Normal
- Height -> Bump or Displacement depending on render setup
