About this asset

This 2K PBR water stain decal adds realistic vertical weathering to architectural surfaces with dedicated opacity and normal maps. This procedural decal captures the organic look of vertical water staining and mineral streaking on exterior or interior walls. The texture features a gradient of muted grey tones transitioning into subtle mossy green hues at the top, simulating moisture accumulation and biological growth. It is designed to be applied as a non-destructive layer over existing concrete, brick, or plaster materials. The kit includes albedo, displacement, normal, roughness, and opacity maps, ensuring that the depth and light reactivity of the streaks remain consistent with the base surface it is applied to during rendering.

The download is an 11.4 MB compressed archive with the texture set at 2K with colour, normal, roughness, displacement and opacity maps, ready for any metal/roughness PBR workflow in Blender, 3ds Max, SketchUp, Unreal Engine or D5.

To integrate this asset, load the albedo, normal, and roughness maps into your material editor's respective slots. Use the provided opacity map in the alpha or transparency channel to ensure the decal blends seamlessly without altering the underlying texture. For best results, use the displacement map to introduce subtle surface depth where the liquid has pooled. Adjust the tiling and scale settings within your host software to match the height of your wall geometry and achieve a natural, non-repeating weathering effect.

Ideal for adding realism to architectural visualisations, this asset is essential for creating aged, neglected, or high-humidity environments. Use it on exterior facades, basement walls, or industrial concrete structures to break up uniform surfaces and introduce a sense of time and environmental exposure. It pairs effectively with weathered concrete, brick, or stone cladding materials. Professionals searching for 'surface imperfections', 'grunge maps', or 'weathering overlays' will find this decal to be a versatile tool for enhancing the authenticity of any 3D environment.
