This seamless dirty brick 3D texture features a classic brick wall constructed from fired clay bricks, arranged in a random bond pattern that enhances visual variety and realism. Each brick exhibits a rough, granular surface characterized by porous microstructures and subtle pits, indicative of weathered and aged masonry. The bricks themselves are composed primarily of silicate-based clay, combined with fine aggregates and mineral pigments that contribute to the natural reddish-brown hues. The mortar joints between bricks show signs of erosion and discoloration, reflecting a weathered cementitious binder that has accumulated grime, moss, and dirt over time. This combination of materials results in a rugged facade with organic imperfections that capture the authentic character of a grimy, neglected brick wall.
The texture utilizes physically based rendering (PBR) principles mapped across multiple channels to deliver photorealistic results. The BaseColor (Albedo) channel accurately portrays the varied brick pigments and stained mortar tones without baked-in shadows, allowing dynamic lighting to interact naturally. The Normal map encodes fine surface details, such as the grainy brick texture and the uneven mortar joints, providing convincing depth and tactile roughness on flat geometry. Roughness maps control the reflectivity, with higher roughness values on the bricks’ porous surfaces and slightly lower values on worn mortar, reproducing the subtle interplay of light and grime. The Metallic channel is kept near zero, reflecting the non-metallic nature of the materials. Ambient Occlusion enhances crevices and joints, emphasizing depth and shadowing, while the Height/Displacement map captures the relief of brick edges and mortar recesses, enabling enhanced parallax effects or tessellation.
Rendered at an ultra-high resolution of 8K, this texture ensures exceptional detail and clarity suitable for close-up shots and large-scale architectural visualizations. It is fully optimized for use in Blender, Unreal Engine, and Unity, providing seamless tiling and precise PBR channel integration for realistic shading across various rendering pipelines. The rough, grainy surfaces and weathered mortar detail respond accurately to environmental lighting conditions, making it ideal for scenes featuring urban decay, industrial environments, or heritage building exteriors that require authentic aged brick appearances.
For practical application, it is recommended to carefully adjust the UV scale to maintain the natural size of bricks, avoiding distortion or repetition artifacts. Additionally, tuning the roughness map can help balance the wetness or dryness of the bricks depending on the environmental context, while blending height and normal maps allows for enhanced surface depth without excessive geometry, optimizing performance while retaining visual fidelity.
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.
