This seamless 3D texture captures the intricate structure of a natural amethyst crystal cluster, characterized by its distinctive geometric formations and rich violet hues. The material is primarily composed of quartz-based substrate with trace amounts of iron and other transition metals that give amethyst its signature purple coloration. The crystal surfaces exhibit sharp, angular facets arranged in a tightly packed cluster pattern, reflecting the natural growth habit of amethyst geodes. The texture emphasizes the complexity of the crystalline lattice, including subtle imperfections and inclusions that contribute to its photorealistic appearance.

The surface finish of the crystals is predominantly polished, with varying levels of translucency and specular reflections that simulate light interaction with the mineral’s smooth, glassy surfaces. The texture maps include a detailed BaseColor (Albedo) channel that replicates the nuanced purple gradients and occasional white or clear quartz areas. The Normal map enhances the perception of depth by accentuating the sharp edges and geometric ridges typical of crystal clusters, while the Height/Displacement map adds realistic surface relief suitable for parallax effects. Roughness values vary across the surface, from highly glossy crystal faces to slightly rougher, weathered edges, enhancing material authenticity without metallic reflections, as the crystals are non-metallic.

The Ambient Occlusion channel provides subtle shadowing in crevices between individual crystal points, enhancing volumetric depth in 3D renders. This texture is created at an 8K resolution, ensuring exceptional detail and sharpness even at close inspection, making it ideal for high-fidelity workflows in Blender, Unreal Engine, and Unity projects. Its seamless design allows for continuous tiling without visible repetition, making it suitable for large surfaces such as geological models, jewelry visualization, or environmental assets where natural crystal formations are required.

For optimal results, it is recommended to carefully adjust the UV scale to match the intended crystal size within your scene, ensuring the pattern maintains its natural proportions. Additionally, fine-tuning the roughness map can help balance reflectivity to simulate either freshly cut or naturally weathered crystal surfaces. Combining subtle parallax displacement with the normal map will enhance the three-dimensionality of the cluster without adding excessive geometry, providing a good balance between visual fidelity and performance.

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.
