Unity Script Reference – Camera.OnPreRender

Camera.OnPreRender

function OnPreRender () : void

Description

OnPreRender is called before a camera starts rendering the scene.

This message is sent to all scripts attached to the camera.

Note that if you change camera's viewing parameters (e.g. fieldOfView) here, they will only take effect the next frame. Do that in OnPreCull instead.

    // This script lets you enable/disable fog per camera.
    // by enabling or disabling the script in the title of the inspector
    // you can turn fog on or off per camera.

    function OnPreRender () {
        revertFogState = RenderSettings.fog;
        RenderSettings.fog = enabled;
    }
    
    function OnPostRender () {
        RenderSettings.fog = revertFogState;
    }
