The Gem Obsidian Precious Rock Stone texture is a meticulously crafted seamless PBR material designed to authentically replicate the natural composition and striking appearance of obsidian a volcanic glass prized for its smooth glossy surface and deep rich black color. This high-quality texture captures the unique mineral structure of obsidian which is characterized by a fine-grained amorphous base substrate formed from rapidly cooled lava. The rapid cooling process prevents crystal formation resulting in a glassy non-crystalline finish that is both visually captivating and scientifically accurate. The texture also incorporates subtle variations in reflectance and smoothness achieved through carefully balanced natural oxide layers and colorants that contribute to the stone’s precious dark palette. These minute details including slight imperfections and surface undulations provide a realistic representation of obsidian’s mineralogical complexity and volcanic origins.

Each PBR channel within this texture is purposefully designed to emphasize obsidian’s distinctive material qualities. The BaseColor (Albedo) channel reveals the rock’s deep black hues with nuanced tonal shifts that simulate the natural interplay of light on its surface. The Normal map highlights fine surface intricacies and gentle waves typical of volcanic glass adding tangible depth and realism. The Roughness map finely controls the polished yet variable shininess allowing for adjustments between a gem-like highly reflective finish and a more subdued matte appearance depending on your visualization needs. The Metallic channel remains minimal to reflect obsidian’s non-metallic nature while the Ambient Occlusion map enhances shadowing in crevices and subtle cavities reinforcing the dimensionality of the stone. Lastly the Height/Displacement map captures the gentle surface relief and micro-texture variations that characterize obsidian’s smooth but imperfect surface finish.

Engineered for seamless large-scale tiling and supporting resolutions up to 8K this texture maintains exceptional clarity and detail across expansive surfaces without visible repetition or seams. It is fully compatible with leading rendering engines such as Blender Unreal Engine and Unity ensuring versatile integration into architectural visualization real-time projects and offline rendering workflows. For optimal results adjusting the UV scale is recommended to balance the level of detail and surface coverage on your models enhancing the natural appearance of the precious rock stone. Additionally fine-tuning the roughness parameter can help achieve the perfect balance of light reflection and shadow highlighting the gem-like qualities of obsidian while preserving its authentic volcanic glass essence.

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.
