This seamless 3D PBR texture depicts a raw emerald crystal characterized by its intricate cleavage planes and diffuse translucency, rendered in ultra-high 8K resolution to capture every fine detail. The material replicates the natural crystalline structure of emeralds, composed primarily of beryllium aluminum silicate, with a complex internal lattice that creates distinct planar fractures—cleavage planes—evident in the texture’s geometric form. These planar breaks lend the pattern a subtle faceted appearance, which is further enhanced by the delicate color zoning typical of emeralds, where varying intensities of rich green hues transition smoothly across the surface, reflecting natural mineralogical variations and trace amounts of chromium and vanadium colorants embedded within the crystal matrix.

The texture’s base color (Albedo) channel accurately represents the translucent green tones with nuanced gradations, while the Normal map emphasizes the finely detailed cleavage planes and microfacet geometry, giving the surface a believable three-dimensional relief. The Roughness map balances the natural gloss and lustrous finish of emeralds, showing areas of polished smoothness interrupted by slightly rougher fracture edges, enabling realistic light scattering and subtle specular highlights. The Metallic channel remains minimal, as emerald is a non-metallic gemstone, but the Ambient Occlusion map adds depth to crevices and fissures, enhancing the perception of volume and internal complexity. The Height/Displacement map is finely tuned to accentuate the planar fractures and subtle undulations of the crystal surface, facilitating convincing parallax effects in real-time renderers.

This texture’s seamless tiling capability ensures it can be applied continuously over large 3D models or environments without visible repetition, ideal for gemstone visualization, realistic mineral formations, or environmental elements requiring natural crystalline detail. The diffuse translucency effect is carefully designed to simulate subsurface scattering within the gemstone, providing a soft glow that modulates light transmission and reflection, which is critical for photorealistic rendering in physically based rendering workflows.

Optimized for use in Blender, Unreal Engine, and Unity, this 8K texture supports advanced shader setups including PBR workflows that rely on accurate material response to lighting. For practical application, it is advisable to adjust the UV scale carefully to maintain the crystal’s natural geometric proportions and to fine-tune the roughness values in conjunction with scene lighting to achieve the desired balance between gloss and diffuse reflection. Additionally, blending height and normal maps can enhance depth perception without excessive computational cost, making this texture both visually rich and performance-friendly for real-time applications.

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.
