Syntax
public static class CameraExtensions
Remarks

This class adds extension methods to the Camera class. It provides helper methods for retrieving the UniversalAdditionalCameraData, and getting and setting volume update settings.

Examples

This sample code shows how to get UniversalAdditionalCameraData and manually update the UnityEngine.Rendering.VolumeStack at runtime.

using UnityEngine;
using UnityEngine.Rendering.Universal;
public class UpdateVolumeStackOnCamera : MonoBehaviour
{
// Reference to the camera component
[SerializeField] private Camera cameraToUpdate;
// Toggle to make the script update the volume framework
[SerializeField] private bool shouldUpdateVolumeFramework;


// Update is called once per frame
private void Update()
{
    // Leave if the volume framework shouldn't be updated
    if (!shouldUpdateVolumeFramework)
        return;

    // Mark that we shouldn't update the volume framework in the next frame
    shouldUpdateVolumeFramework = false;

    // Check if we have a reference to the camera
    if (cameraToUpdate == null)
    {
        Debug.LogError("UpdateVolumeStackOnCamera.Update(): cameraToUpdate has not been assigned.");
        return;
    }

    // Make the camera use the ViaScripting mode so the volume framework only updates when the script calls UpdateVolumeStack().
    VolumeFrameworkUpdateMode volumeFrameworkUpdateMode = cameraToUpdate.GetVolumeFrameworkUpdateMode();
    if (volumeFrameworkUpdateMode != VolumeFrameworkUpdateMode.ViaScripting)
    {
        cameraToUpdate.SetVolumeFrameworkUpdateMode(VolumeFrameworkUpdateMode.ViaScripting);
    }

    // Update the volume framework
    cameraToUpdate.UpdateVolumeStack();
}

}
