This seamless 3D PBR texture represents a high-fidelity obsidian surface characterized by its naturally glassy, smooth substrate interspersed with intricate fractures and fine crystal shards. The base material is volcanic glass—obsidian—known for its amorphous, non-crystalline structure that provides a predominantly smooth and reflective plane. These glassy surfaces are punctuated by subtle fissures and irregular fractures, which are rendered with precise height and normal mapping to convey depth and complexity. The texture’s low porosity and weathering resistance contribute to its polished appearance, while minor inclusions of crystalline aggregates create localized variations in reflectivity and translucency.

The material composition is reflected in the PBR channels with a rich BaseColor (Albedo) map capturing the deep black to charcoal hues of obsidian, enhanced by subtle variations where fractures and crystal shards scatter light differently. The Normal map accentuates the micro-geometry of the surface fractures and the subtle undulations of the glassy plane, adding realistic surface detail. Roughness is finely tuned to replicate the lustrous finish of obsidian—mostly smooth with areas of slightly increased roughness where fractures diffuse reflections. The Metallic channel is used sparingly to introduce a subtle metallic sheen highlight along fracture edges and crystal facets, simulating the reflective qualities of embedded mineral inclusions. Ambient Occlusion enhances the visual weight of crevices and micro-voids, while Height/Displacement maps provide the necessary relief for realistic parallax and depth effects in real-time engines.

This 8K resolution texture is optimized for seamless tiling, ensuring no visible repetition or seams when applied across large surfaces. Its high resolution preserves intricate detail, making it ideal for close-up renders in Blender as well as real-time applications in Unreal Engine and Unity. The combination of detailed normal and height maps with calibrated roughness and metallic values allows for flexible shading adjustments depending on lighting conditions and scene requirements.

For practical use, it is recommended to carefully adjust the UV scale to maintain the natural grain and fracture density of obsidian without overstretching, which could distort the crystalline details. Additionally, fine-tuning roughness values can help balance between a high-gloss glassy appearance and the subtle matte diffusion seen on fractured edges. Blending height and normal maps can also enhance the three-dimensional illusion of the fractures and crystal shards, especially when used with parallax occlusion mapping or tessellation features in modern rendering pipelines.

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.
