Blender-style screen-space cavity and curvature effect for Unity 6 URP, with adjustable ridges, valleys, colors, quality modes, debug views, and Volume support.Enhance surface definition and small geometric detail with a Blender-style screen-space cavity and curvature effect for Unity 6 URP.Screen Space Cavity & Curvature analyzes the camera depth and normal buffers to emphasize recessed details, convex edges, and concave surfaces in real time. It can improve the readability of vehicles, environments, props, architecture, and stylized scenes without requiring additional textures or changes to existing materials.The effect integrates directly with Unity’s Volume framework and supports both Global and Local Volumes. All major settings can be adjusted at runtime, including cavity strength, curvature intensity, radius, colors, distance fading, quality, and debug visualization.Designed for Unity 6 URP, the package includes support for the RenderGraph rendering path as well as Compatibility Mode.Key FeaturesBlender-style screen-space cavity enhancementConvex ridge highlightingConcave valley darkeningIndependent cavity, ridge, and valley controlsCustom colors for each effect channelAdjustable sampling radius and intensityDepth rejection to reduce edge halosCamera-distance fadingLow, Medium, and High quality presetsMultiple debug visualization modesGlobal and Local Volume supportRuntime parameter controlUnity 6 RenderGraph supportURP Compatibility Mode supportForward and Deferred renderer supportNo changes required to standard URP materialsSuitable for vehicles, props, architecture, and environmentsIdeal ForRacing and driving gamesStylized gamesVehicle presentationArchitectural visualizationProduct visualizationEnvironment artTechnical and debug renderingScenes that require stronger geometric readabilityPackage Content Disclaimer: The package includes the Screen Space Cavity & Curvature effect, source code, shader, documentation, and a demonstration scene containing a small Funbooster logo model, one texture, one mesh, and a prefab.All other vehicles, props, materials, and models shown in promotional screenshots are used for demonstration purposes only and are not included.Unity and the Unity logo are trademarks of Unity Technologies.

Only surfaces visible to the camera can contribute to the result.Hidden, occluded, and off-screen geometry cannot affect the effect.Transparent objects may not contribute unless their shaders write compatible depth and normal information.Strong depth discontinuities can produce screen-space artifacts when extreme radius or intensity values are used. The included depth-threshold control can reduce these artifacts.Source CodeFull C# and shader source code is included.The source can be modified to integrate the effect with custom rendering systems, gameplay logic, or project-specific visual requirements.
