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.

Also note that when OnPreRender is called, the camera's render target is not set up yet, and the depth texture(s) are not rendered yet either. If you want to do something later on (when the render target is already set), try using a CommandBuffer.

See Also: onPreRender delegate.

using UnityEngine;

public class Example : MonoBehaviour { // 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.

bool revertFogState = false;

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

void OnPostRender() { RenderSettings.fog = revertFogState; } }
