This high-quality seamless 3D texture represents a coarse geological rock surface characterized by its rough uneven stone face with natural dirt and weathering effects. The base substrate mimics mineral-rich sedimentary stone combining granular aggregates and fine particles that create a porous rugged terrain typical of outdoor rock formations. The surface finish is markedly raw and unpolished highlighting natural variations in color and texture from embedded oxide layers and subtle dirt deposits. These details contribute to an authentic rock face appearance displaying a balance of coarse grain orientation and weathered erosion that evokes real-world geological complexity. The physically based rendering (PBR) workflow ensures this texture captures the interplay of light and material properties accurately suitable for modern pipelines in Blender Unreal Engine and Unity.

Within the PBR maps the Albedo channel delivers the base color with natural earth tones and dirt overlays while the Normal map encodes fine surface irregularities and coarse rock grain enhancing the tactile roughness without additional modeling. The Roughness map controls the stone’s matte finish reflecting the weathered dusty quality typical of outdoor terrain. The Height map provides precise displacement data for uneven surfaces enabling realistic parallax and depth effects. Ambient Occlusion emphasizes crevices and shadowed areas to boost visual depth and natural shading consistency. This texture excludes metallic elements reinforcing its purely geological non-metallic stone nature. Both 4K and optional 8K resolutions are provided allowing for high-detail applications in real-time and offline renderers across digital content creation suites and game engines.

Optimized for use as rock 2 in various projects this texture performs reliably without manual tweaking balancing detail and performance to suit diverse scales and environments. It excels in outdoor and natural terrain scenarios where the coarse dirty stone surface adds realism and depth. For best results it is recommended to adjust the UV scale to match the intended rock size and to fine-tune roughness values slightly to match specific lighting conditions or material wear levels. The inclusion of multiple PBR channels in PNG and EXR formats ensures compatibility and flexibility across workflows supporting consistent shading and rendering quality in both real-time engines like Unreal Engine and Unity as well as offline renderers in Blender.

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.
