The Discolored Dirty Stone texture is a physically based seamless 3D texture designed to replicate a natural rock surface with a weathered rough and coarse appearance. This material simulates the complex interplay of minerals fine aggregates and organic dirt deposits typically found on stone boulders exposed to outdoor environments. The base substrate resembles a dense sedimentary rock with subtle porous features and uneven grain orientation capturing the natural imperfections caused by prolonged exposure to elements oxidation and discoloration. The surface finish is matte and unpolished emphasizing the gritty dirty look that results from accumulated grime and mineral staining. Pigments and oxide layers are subtly embedded within the albedo channel to represent these discolorations enhancing realism across various lighting conditions and rendering engines.

In terms of PBR channels the texture set includes high-resolution 4K maps with an optional 8K upgrade ensuring detailed crisp visuals suitable for modern pipelines in Blender Unreal Engine and Unity. The Albedo (BaseColor) map conveys the nuanced color variations and dirt overlays while the Normal map defines the intricate bumps and coarse surface irregularities characteristic of weathered stone. The Roughness channel effectively balances the matte non-reflective finish of the rock surface supporting consistent shading without manual adjustments. Ambient Occlusion enhances depth perception by accentuating crevices and natural indentations and the Height map provides precise displacement data to simulate surface relief and subtle erosion effects. This comprehensive PBR suite supports metal/rough workflow calibrations enabling reliable physically accurate rendering in both real-time and offline engines.

Optimized for seamless tiling this texture performs efficiently across digital content creation software and game engines delivering a harmonious balance between detail and performance. Its coarse and natural stone qualities make it ideal for use in environmental scenes that require authentic rocky surfaces such as cliffs boulders or rugged terrain. For best results it is recommended to carefully adjust the UV scale to maintain realistic grain size and to fine-tune the roughness parameter slightly depending on scene lighting and moisture effects. The height map can also be leveraged for subtle parallax or displacement effects to enhance depth without sacrificing 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.
