This seamless 3D texture presents an 8K photorealistic rendering of gypsum crystalline formations, characterized by their naturally rough and faceted surfaces. The material composition reflects gypsum’s typical calcium sulfate dihydrate structure, where the crystalline substrate forms interlocking angular crystals with translucent qualities. The rough crystal surfaces exhibit subtle micro-faceting, which enhances the light refraction and scattering effects, contributing to the realistic portrayal of mineral inclusions and natural fractures. These crystalline structures are arranged in a veined and clustered pattern, creating an organic yet repetitive tessellation ideal for seamless tiling on 3D models.

The texture’s base color channel (Albedo) captures the delicate off-white to pale beige hues intrinsic to gypsum, with slight variations caused by embedded impurities and mineral veining. The Normal and Height maps define the pronounced geometric relief of the crystal facets, emphasizing the jagged edges and fine granular details of the rough surfaces. Roughness values vary across the surface, with polished areas reflecting more light and rougher zones diffusing it, simulating the mineral’s semi-glossy finish. The Metallic channel remains near zero, as gypsum is non-metallic, while Ambient Occlusion enhances the depth perception within crevices and between crystal clusters, accentuating the complex geometry.

Porosity and subtle weathering effects are evident in the texture, modeled through micro-surface imperfections and slight wear on the crystal edges, suggesting natural erosion and mineral growth patterns. The surface finish balances between semi-polished crystalline facets and rough, matte inclusions, providing a versatile PBR material that reacts realistically under various lighting conditions. This texture is optimized for high-fidelity rendering in Blender, Unreal Engine, and Unity, ensuring consistent appearance across diverse workflows and real-time applications.

For practical use, it is advisable to carefully adjust the UV scale to maintain the natural grain and avoid repetition artifacts, especially when applied to large surfaces. Additionally, fine-tuning the roughness channel can enhance realism by increasing glossiness on selected crystal facets, while blending height and normal maps can improve the perception of depth without compromising performance. This approach allows for a highly detailed, physically accurate gypsum crystalline texture suitable for architectural visualization, geological models, and detailed mineral studies within 3D environments.

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.
