This seamless 3D PBR 8K texture captures the intricate composition of natural onyx stone, characterized by its smooth veins and distinctive mineral inclusions. The base material consists primarily of fine-grained calcite and quartz crystals, forming translucent layers that are visible beneath the polished surface. These layers create a subtle depth effect, enhanced by the interplay of light within the stone’s crystalline structure. The texture’s geometric form is veined and laminated, with natural mineral veins flowing organically, contributing to the realistic complexity of the pattern. The polished finish replicates the stone’s natural shine, resulting in a reflective surface that emphasizes the depth and clarity of the onyx inclusions.
The substrate of this onyx texture is dense and low-porosity, typical of high-quality natural onyx, which minimizes weathering and surface imperfections. The material composition involves tightly bound crystalline aggregates that yield a smooth yet varied surface, with subtle undulations and micro-fissures visible in the normal and height maps. The BaseColor (Albedo) channel accurately reproduces the warm, semi-translucent hues of the stone, while the Normal map highlights the fine details of the crystal structure and mineral veins. Roughness values are calibrated to maintain a polished finish with low surface roughness, allowing for natural reflections and highlights, while the Ambient Occlusion map enhances perceived depth in recessed vein areas. The Metallic channel remains neutral, as onyx is non-metallic, ensuring realistic light interaction without unwanted metallic sheen.
This texture is optimized for use in Blender, Unreal Engine, and Unity, providing a high level of detail suitable for close-up renders and architectural visualizations. The 8K resolution ensures crisp display of fine veins and crystal inclusions, making it ideal for projects requiring photorealistic natural stone materials. The Height/Displacement map supports subtle parallax and displacement effects, adding physical depth to 3D surfaces when used properly. For practical use, it is recommended to adjust the UV scale to achieve a natural vein repetition and to fine-tune roughness levels depending on lighting conditions—lower roughness values under bright, direct light enhance the polished shine, while slightly increased roughness suits softer, diffused environments. Blending the height map with normal details can further enhance the tactile realism of the onyx surface.
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
