Dark Grey Liquid Leak PBR Decal

This 2K PBR decal provides a realistic dark grey liquid leak effect, designed for layering over surfaces to add weathered detail. This procedural decal features a series of vertical, gravity-driven streaks that simulate liquid run-off or staining. The texture is designed with high-contrast tonal variations to mimic natural weathering, appearing as dark, viscous drips against a substrate. It includes a comprehensive map set comprising albedo, displacement, normal, roughness, and metalness channels. The inclusion of a dedicated opacity map allows for precise non-destructive layering, ensuring the decal integrates seamlessly onto existing materials without obscuring underlying textures. The pattern is generated to avoid visible tiling artefacts, maintaining a realistic, organic appearance across large surfaces.

The download is a 4.6 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.

Professionals can integrate this decal by applying it as a secondary layer within a standard shader graph or material stack. Use the provided opacity map to mask the effect onto specific areas of a geometry, such as wall corners or around pipe penetrations. The normal and displacement maps can be adjusted to control the perceived depth and light reaction of the streaks. It is highly effective when blended with base materials to break up repetitive tiling and add environmental storytelling.
