This seamless 3D PBR 8K texture captures the distinctive characteristics of onyx stone, emphasizing its natural fissures and rough surface texture. Onyx, a form of sedimentary chalcedony, features an intricate pattern of mineral veins that traverse its coarse grain structure, creating a visually rich and earthy-toned surface. The base material is essentially a fine crystalline quartz substrate, with silica acting as the main binder, holding together layers of microcrystalline aggregates. This natural composition results in a semi-translucent stone with visible stratifications and subtle variations in opacity and color, ranging from warm beige and brown hues to deeper earthy tones. The texture’s fissures and mineral veins reveal the geological processes of sedimentation and weathering, adding depth and authenticity to the material’s form.
The geometric form of this texture is defined by irregular, organically shaped fissures and vein patterns, which are characteristic of onyx’s natural formation. The surface finish is intentionally rough and raw, reflecting the unpolished state of natural onyx stone exposed to erosion and environmental aging. This coarse grain finish enhances tactile realism, with subtle porosity and micro-cracks that contribute to light scattering and shadowing effects. The mineral veins, composed primarily of calcite or other secondary mineral deposits, provide contrasting linear details that break up the base color and introduce a natural variability essential for high-fidelity rendering. These veins and fissures are captured in the height and normal maps, giving a pronounced three-dimensional relief that reacts accurately to lighting conditions.
In the PBR workflow, the BaseColor (Albedo) map represents the warm, earthy tones and natural mineral coloration of the onyx, without baked-in shadows to ensure versatility under varying lighting. The Normal map encodes the fine roughness and fissure details, enhancing the perception of depth and texture. The Roughness channel reflects the raw, unpolished surface, with moderate to high roughness values that simulate the stone’s matte finish and diffuse reflection. The Metallic map remains at zero, as onyx is a non-metallic mineral. Ambient Occlusion accentuates the crevices and fissures, adding realistic shadowing to the stone’s natural indentations. The Height or Displacement map provides additional geometric detail to enhance parallax effects in real-time engines or displacement in offline renders.
Designed for compatibility and ease of use, this 8K resolution texture is optimized for seamless tiling, making it suitable for large-scale architectural visualizations, environmental effects, and game asset materials in Blender, Unreal Engine, and Unity. To achieve the best visual results, it is recommended to adjust UV scaling carefully to avoid repetition artifacts and to fine-tune roughness values according to scene lighting and desired surface reflectivity. Additionally, blending height and normal maps can help create more nuanced surface relief, especially when simulating light interaction on the fissures and coarse grains, enhancing realism without heavy geometry.
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
