Generate concrete with rebar grid and crack controls.
Concrete Rebar Texture Generator is a browser-based procedural texture tool specialized in concrete, rebar, construction surfaces for concrete and cementitious material simulation. It provides real-time parameter control with 4 tunable properties, generating seamless, tileable textures with complete PBR map output. Generate concrete with rebar grid and crack controls. The generated maps are compatible with all major 3D applications including V-Ray, Corona, Blender Cycles, Unreal Engine, requiring no plugins or installation.

Concrete textures must capture both the aggregate-scale variation and the fine-scale cement paste surface. The Height map is critical for reproducing formwork impressions, bug holes, and surface defects that give concrete its characteristic industrial aesthetic. Concrete Rebar Texture Generator specifically targets concrete, rebar, construction characteristics, using layered procedural algorithms to produce results that are visually comparable to photoscanned references while remaining fully parametric. Unlike static textures, every adjustment you make regenerates the complete PBR stack in real time — changing one parameter instantly updates the Base Color, Normal, Roughness, and Height channels simultaneously. This ensures all maps remain physically consistent with each other, preventing the visible artifacts that can occur when mixing maps from different sources.
Understanding what each control does helps you reach the look you want faster. **BarSpacing** — Adjusts the barspacing property of the generated texture. **BarThickness** — Adjusts the barthickness property of the generated texture. **CrackAmount** — Adjusts the crackamount property of the generated texture. The Roughness parameter deserves special attention: Concrete roughness depends on the finish — form-finished concrete has moderate roughness, while broom-finished or acid-etched concrete is significantly rougher. A recommended workflow is to lock your Base Color first, then shape the macro form with the primary detail parameter, and only then refine roughness and secondary controls. This prevents the common mistake of over-tweaking multiple sliders simultaneously and losing track of what produced a good result.
The concrete, rebar, construction characteristics of this generator make it particularly effective for **Brutalist architecture visualization**, **Infrastructure engineering**, **Industrial interior design**, **Urban decay environments**. In game development, use the generated maps directly in V-Ray, Corona, Blender Cycles, Unreal Engine by importing the exported PNG or JPG files into your material editor. For film and commercial work, the 4096×4096 export resolution provides sufficient detail for full-frame closeup shots. When working in tiled environments (floors, walls, terrain), the seamless tiling guarantee means you can apply the material at any UV scale without visible repetition boundaries.
Before exporting, switch between the Base, Height, Roughness, and Normal preview modes to verify that all four maps tell a consistent physical story. A common pitfall is adjusting parameters while viewing only the Base Color and then discovering that the Height map produces unwanted displacement spikes. Export all four maps at the same resolution to maintain texel density consistency. When importing into PBR-compatible engines, assign the Base Color to the Albedo/Diffuse slot, the Normal map to the Normal input (ensure "Normal Map" format is selected), the Roughness map to the Roughness/Smoothness channel (invert for engines that use Smoothness), and the Height map to Displacement or Parallax Occlusion inputs. For Unreal Engine and Unity, applying these maps to a standard PBR material will produce physically accurate results out of the box.

Yes. All textures produced by this generator tile seamlessly — no visible seams when repeated on large surfaces.
You can export Base Color, Height, Normal, and Roughness maps, ready to drop into any PBR workflow in Blender, Unity, or Unreal Engine.
Yes. All textures generated by Concrete Rebar Texture Generator are free for both personal and commercial use. You can export and use the PBR maps in games, films, product renders, and print materials without attribution requirements.
Concrete Rebar Texture Generator generates four PBR texture maps: Base Color (Albedo), Normal Map, Roughness Map, and Height Map. These are compatible with all physically based rendering engines including Blender Principled BSDF, Unreal Engine material system, Unity Standard/HDRP, V-Ray, and Arnold.
Yes, every output is mathematically guaranteed to tile seamlessly in all directions. You can apply the texture at any UV scale without visible seams or repetition boundaries. Verify tiling by switching to the 3D preview mode and increasing the UV tiling setting.
You can export textures up to 4096×4096 pixels. For real-time applications like games, 2048×2048 is usually sufficient. For film, VFX, or print work, the full 4096 resolution provides enough detail for extreme closeups.
The Height map represents surface elevation — white areas are raised, dark areas are recessed. In Blender, connect it to a Displacement node. In Unreal Engine, use it as a World Position Offset or Tessellation input. In Unity HDRP, apply it to the Displacement Map slot and enable tessellation on the material.
