This seamless 3D texture represents a faceted ruby gemstone rendered in ultra-high 8K resolution, designed to faithfully replicate the material and optical properties of a polished gem surface. The base material is crystalline corundum, where aluminum oxide forms a dense, hard substrate with minimal porosity. The intense red coloration arises from trace chromium ions acting as natural pigments within the crystal lattice. The geometry captures a precise, multi-faceted cut typical of fine gemstones, with sharp crystal edges and symmetrical planes that reflect and refract light dynamically. These facets are modeled to simulate the complex interplay of internal refraction and external reflection, essential for conveying the characteristic brilliance and fire of a ruby.

The texture’s surface finish is meticulously polished, resulting in highly reflective facets with low roughness values mapped in the PBR roughness channel to ensure crisp specular highlights. The BaseColor (Albedo) channel conveys the rich, saturated crimson hues with subtle color zoning to simulate natural variations found in genuine stones. Normal and Height maps define the sharp facet edges and subtle micro-geometry, enhancing the three-dimensionality and depth perception when applied in 3D environments. The Metallic channel is set close to zero, consistent with the non-metallic nature of corundum, while the Ambient Occlusion map accentuates the shadows between facets, adding realism by simulating light occlusion in crevices.

Designed for seamless tiling, this texture supports realistic application across curved or complex surfaces without visible repetition, making it suitable for detailed close-ups or large-scale visualizations. Its compatibility with Blender, Unreal Engine, and Unity ensures broad usability in digital content creation workflows, enabling artists to leverage the texture’s high fidelity in real-time rendering or offline ray tracing. The 8K resolution allows for exceptional detail preservation, crucial for projects requiring macro-level scrutiny of gemstone surfaces.

For optimal results, it is recommended to carefully adjust the UV scale to maintain facet proportions relative to the model’s size, preventing distortion of the gem’s geometry. Additionally, tuning the roughness parameters allows control over the polish level, from a mirror finish to slightly more diffuse reflections, depending on the desired artistic effect. Combining the Height map with normal mapping can enhance the perception of depth and refraction on the facets, especially when using parallax occlusion techniques, further increasing realism in interactive 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.
