This seamless 3D texture showcases an 8K PBR cracked basalt stone surface, meticulously crafted for rugged terrain modeling and realistic environmental design. Basalt, a dense volcanic igneous rock, forms the primary base material here, characterized by fine-grained mineral aggregates and a low porosity substrate. The texture captures the natural fractured geometry typical of basalt cliffs and rubble, featuring sharp, jagged edges and irregular stone fragments that break up the surface into distinct basalt columns and shards. These elements create an authentic representation of basalt’s solid yet fractured form, with subtle stone pores and grain details enhancing the tactile complexity.
The material’s composition reflects a naturally occurring volcanic stone: the substrate is a compact matrix of fine-grained minerals bonded tightly, with weathered cracks and fissures resulting from environmental stress. The texture’s surface finish simulates a slightly rough, matte basalt surface with minimal metallic properties, emphasizing its non-reflective, natural stone appearance. Coloration is dominated by deep charcoal grays and muted black tones with subtle variations caused by mineral impurities and weathering effects, accurately mapped in the BaseColor (Albedo) channel. The Normal and Height/Displacement maps highlight the intricate cracks, jagged edges, and porous stone grains, providing pronounced depth and surface relief suitable for close-up viewing.
Roughness mapping is carefully calibrated to reflect the basalt’s uneven and weathered surface—areas around cracks and stone fragments exhibit higher roughness for diffuse light scattering, while flatter basalt faces show moderately smoother characteristics. The Ambient Occlusion channel enhances shadowing in crevices and under overlapping stone fragments, adding dimensionality and realism. The texture is non-metallic, so the Metallic channel is set to zero, consistent with natural basalt’s composition. This comprehensive PBR setup ensures compatibility and optimal visual fidelity across Blender, Unreal Engine, and Unity, supporting high-resolution rendering workflows and physically accurate shading.
Designed for seamless tiling, this texture allows for expansive coverage of rocky terrains without visible repetition or seams, making it ideal for large environment assets such as stone cliffs, rugged landscapes, and volcanic rock formations. For practical application, it is recommended to adjust the UV scale based on the model’s dimensions to maintain natural detail density and avoid pixelation. Additionally, fine-tuning roughness values can help achieve the desired balance between matte and slightly polished basalt surfaces, while blending Height and Normal maps can enhance parallax effects for added surface depth during close camera interactions.
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)
- Enable the addon: Edit → Preferences → Add-ons → Node Wrangler.
- Create a material and select the Principled BSDF node.
- 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.
- Add AO and Height using the “Manual wiring” steps below (5 and 6).
Manual wiring (full control)
- Create a material (Material Properties → New) and open the Shader Editor.
- Add an Image Texture node for each map. Set Color Space:
- Albedo → sRGB
- AO, Roughness, Metallic, Normal, Height, ORM → Non-Color
- Connect to Principled BSDF:
albedo → Base Colorroughness → Roughnessmetallic → Metallic (for wood this often stays near 0)normal → Normal Map node (Type: Tangent Space) → Normal of Principled.
If details look “inverted”, enable Invert Y on the Normal Map node.
- 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).
- Height / Displacement:
Cycles — true displacement
- Material Properties → Settings → Displacement: Displacement and Bump.
- Add a Displacement node: connect
height → Height, set Midlevel = 0.5, Scale = 0.02–0.08 (tune to taste).
- Output of Displacement → Material Output → Displacement.
- Add geometry density (e.g., Subdivision Surface) so displacement has polygons to work with.
Eevee (or lightweight Cycles) — bump only
- Add a Bump node:
height → Height.
- 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:
- Add one Image Texture (Non-Color) → Separate RGB (or Separate Color).
- R (red) → AO (use it in the Multiply node with albedo as above).
- G (green) → Roughness of Principled.
- B (blue) → Metallic of Principled.
UVs & seamless tiling
- These textures are seamless. If your mesh has no UVs, go to UV Editing → Smart UV Project.
- 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.
