Fog

The effect descriptions on this page refer to the default effects found within the post-processing stack.

Fog is the effect of overlaying a color onto objects dependant on the distance from the cameraA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info

. This is used to simulate fog or mist in outdoor environments and is also typically used to hide clipping of objects when a __camera__’s far clip plane has been moved forward for performance.

The Fog effect creates a screen-space fog based on the camera’s depth texture. It supports Linear, Exponential and Exponential Squared fog types. Fog settings should be set in the Scene tab of the Lighting window.

Settings. The parameters for the Post-processing fog are mirrored from the Fog parameters set in the Scene tab of the Lighting window. This ensures forward rendered objects will always receive the same fog when rendering in deferred.

Requirements

  • Depth texture

  • ShaderA small script that contains the mathematical calculations and algorithms for calculating the Color of each pixel rendered, based on the lighting input and the Material configuration. More info
