About this asset

This 2K PBR decal provides realistic vertical rain streak weathering, designed for layering over architectural surfaces. This procedural grunge decal captures the subtle, organic pattern of water dripping down a vertical surface. The texture consists of thin, elongated streaks that vary in intensity, mimicking natural weathering caused by rain exposure on facades or interior walls. As a PBR-ready asset, it includes comprehensive maps for albedo, displacement, normal, roughness, and metalness, ensuring the streaks react correctly to environmental lighting. The inclusion of a dedicated opacity map allows for precise blending, enabling designers to overlay these marks onto existing materials without disrupting the underlying surface properties or texture mapping.

The download is a 2.6 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.

Apply this decal as a secondary UV layer or a blend material in your rendering software to introduce realistic wear. Use the provided opacity map to define the influence of the streaks on the base surface. Because the texture is derived from a procedural graph, it maintains high fidelity across large areas. Adjust the normal and displacement intensity to control the depth of the streaks, ensuring they integrate naturally with the material finish of the host object.

Integrate these rain streaks into exterior facade visualisations, industrial warehouse scenes, or weathered urban environments to add a layer of authentic ageing. It is particularly effective for concrete, metal cladding, or painted surfaces where water run-off marks are expected. Professionals can use this to break up repetitive textures, adding visual interest to otherwise uniform building components. Pair with high-quality concrete or steel shaders to enhance the sense of realism in both architectural renderings and environmental game assets during the final detailing stage.
