About this asset

This vertical water staining decal features a subtle, elongated streak pattern characteristic of moisture runoff on exterior or interior walls. The texture captures the organic, irregular nature of mineral deposits and grime accumulation, with a dense top point that tapers into a faint, diffused trail. It is designed to simulate natural weathering processes, providing a high-fidelity visual detail that sits effectively on concrete, stone, or painted finishes. The included opacity map ensures clean blending, allowing the stain to integrate seamlessly with underlying materials without creating harsh edges or unwanted background artifacts in your scene.

The download is a 14.2 MB compressed archive with the texture set at 2K with colour, normal, roughness, ambient occlusion, displacement and opacity maps, ready for any metal/roughness PBR workflow in Blender, 3ds Max, SketchUp, Unreal Engine or D5.

To integrate this decal, apply it as a layered texture within your preferred rendering engine's material editor. Use the provided opacity map in the transparency slot to mask the background, ensuring the stain interacts correctly with the surface below. For added realism, map the normal and displacement files to the same UV coordinates to simulate the slight surface erosion often associated with long-term water exposure. Adjust the roughness map to differentiate the stain's finish from the surrounding material's sheen.

Ideal for architectural visualisers working on exterior facade studies, this decal adds essential realism to concrete walls, masonry, or rendered surfaces subject to environmental wear. It is particularly effective for urban environments, industrial sites, or aged residential projects where subtle weathering is required to break up clean geometry. Use it to enhance the realism of building corners, parapets, or areas beneath window sills where water runoff naturally collects. It pairs well with other dirt, grime, and environmental assets to create authentic, lived-in architectural spaces.
