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.
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
