Weathered Grey Water Leak PBR Decal

This 2K PBR decal provides a realistic grey water leak effect, featuring separate opacity maps for non-destructive surface layering. This high-resolution PBR decal captures the vertical streaking and heavy mineral staining characteristic of prolonged water ingress on concrete or masonry facades. The texture features a realistic gradient of grey and off-white tones, with denser, darker saturation at the top edge tapering into lighter, irregular drips. Designed to simulate moisture damage, the asset includes albedo, displacement, normal, and roughness maps to ensure accurate light interaction and physical depth. The separate opacity channel allows for precise blending, enabling the user to overlay the leak onto existing materials without disrupting the base surface properties.

The download is a 10.9 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.

Professionals can integrate this decal into rendering pipelines by applying it as a secondary material layer or using a decal projection node. By utilizing the provided opacity map, users can mask the texture over concrete, brick, or stucco shaders. Adjusting the displacement map strength allows for subtle surface relief, while the roughness map ensures that the wet, stained areas react correctly to scene lighting. This workflow maintains the integrity of the underlying material while adding essential photorealistic weathering.
