Fullscreen height fog for URP with procedural noise, directional scattering, fog lights, and Volume controls. Single-pass, no raymarching, Render Graph native.Super Fog adds ground fog to your URP project through a single fullscreen post-processing pass. It uses an analytical Beer-Lambert integral to compute fog density — no raymarching, no 3D textures, no baked data. The result is a volumetric-looking fog layer that runs at constant cost per pixel regardless of fog thickness or scene complexity.The fog sits at a configurable world-space height and fades vertically using an exponential falloff. You control density, height, base position, and distance range directly from a Volume override, so everything works with URP's built-in blending between volumes. This makes it straightforward to set up different fog zones for interiors, exteriors, swamps, valleys, whatever your scene needs.Three procedural noise types (Value, Perlin, Simplex) break up the fog shape with scrolling FBM patterns. The noise runs entirely in the shader with no texture lookups, keeping memory usage flat. You can adjust octave count, lacunarity, persistence, scroll speed, and vertical influence to get anything from slow-rolling mist to fast turbulent clouds.Directional scattering simulates light from the main directional light bleeding through the fog useful for sunrise, sunset, and god-ray-style looks. You set the intensity, tightness, and colour of the scatter independently from the fog colour itself.Fog Lights let Point and Spot lights in your scene punch through the fog with a fake volumetric glow. The system picks up to 8 visible lights per frame from URP's culling results, compresses their intensity logarithmically, and blends their contribution along the camera ray. No extra passes, no shadow maps just a per-pixel loop inside the same fullscreen shader.The colour system gives you separate base, top, and distance colours with a power-curve height gradient and a distance blend parameter. Combined with HDR colour support and alpha control, you can dial in anything from thick white ground mist to coloured toxic haze.Built for Unity 6 and URP 17+.
