About this asset

This 2K PBR decal provides a realistic concrete leaking stain for architectural visualisations, supplied with essential map channels. Designed as a procedural grunge element, this leaking stain decal replicates the subtle, streaking patterns typical of weathered concrete surfaces. The asset includes a comprehensive set of PBR maps: albedo, displacement, normal, roughness, and metalness, ensuring accurate interaction with light and shadow. By utilizing a separate opacity channel rather than a baked-in alpha, the decal allows for precise layering over existing base materials without disrupting their underlying texture or properties. The result is a clean, non-repeating overlay that adds necessary visual realism to architectural surfaces in both interior and exterior environments.

The download is a 2 MB compressed archive with the texture set at 2K with colour, normal, roughness, metalness, displacement and opacity maps, ready for any metal/roughness PBR workflow in Blender, 3ds Max, SketchUp, Unreal Engine or D5.

Professionals can integrate this decal by applying it as a secondary material layer or a blended texture node within their rendering engine. It is ideal for breaking up repetitive tiling surfaces or adding age to clean facades. Users should map the opacity channel to the material's cutout or transparency slot to maintain the integrity of the surface beneath, while the displacement and normal maps provide depth to the stain against the host material.

This asset is essential for project stages requiring high-fidelity weathering, such as concept development, detailed visualisations, and post-production refinement. It belongs in architectural scenes focusing on brutalist, industrial, or urban contexts where concrete elements are prominent. Designers use these maps to add character to retaining walls, exposed structural columns, or exterior cladding panels. It pairs effectively with other grunge and surface imperfection assets to create a layered, realistic aesthetic that avoids the artificial look of overly pristine 3D materials.
