This Rock Boulder Coarse 3D texture is a seamless tileable physically based rendering (PBR) material designed to replicate the natural appearance of bare coarse geological stone found in rugged outdoor terrain. The base substrate mimics rough uneven rock faces composed primarily of mineral aggregates tightly bonded with natural cementing agents resulting in a porous and weathered surface. The texture captures subtle variations in grain orientation and surface erosion reflecting natural weathering processes that give the boulder its distinct coarse character. Colorants are represented through earthy pigments and oxide layers that create a balanced palette of muted browns grays and occasional rust tones enhancing the natural stone's authenticity without artificial gloss or polish.

In the PBR workflow this texture includes high-resolution 4K maps with an optional 8K version for demanding high-end visualizations in Blender Unreal Engine and Unity. The Albedo/BaseColor map accurately portrays the stone’s natural coloration and pigment distribution while the Normal map emphasizes the uneven rough rock face structure by simulating fine surface details and depth. The Roughness channel is finely calibrated to reflect the coarse matte finish typical of bare rock ensuring realistic light diffusion without metallic reflections as this geological stone lacks metallic properties. Ambient Occlusion enhances shadowing in crevices and cracks and the Height/Displacement map provides precise elevation data to support realistic parallax and depth effects in real-time and offline renderers contributing to the overall tactile feel of the terrain.

Optimized for modern pipelines this texture supports the metal/rough workflow and features calibrated shading to deliver reliable consistent results across various DCC applications and game engines without requiring manual tweaking. For practical use it is recommended to carefully adjust the UV scale to match the actual size of rock formations in your scene as this ensures the coarse detail is both visually convincing and performance-efficient. Additionally fine-tuning the roughness parameter can help simulate different weathering stages or moisture levels on the rock surface enhancing realism. This seamless PBR 3D texture is a versatile solution for creating natural stone boulders and rocky outdoor terrain that demands both visual fidelity and optimized 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.
