RTClearFlags

설명

Flags that determine which render targets Unity clears when you use CommandBuffer.ClearRenderTarget.

You can combine flags by using the bitwise OR operator.

using UnityEngine;
using UnityEngine.Rendering;

// Attach this script to a Camera and select a Clear Mode.
// When you enter Play mode, a command buffer clears the screen with different clear parameters.
[RequireComponent(typeof(Camera))]
public class MyClearScript : MonoBehaviour
{
    public enum ClearMode
    {
        All,
        ColorStencil
    }

    public ClearMode m_ClearMode;

    void Start()
    {
        var camera = GetComponent<Camera>();
        var buffer = new CommandBuffer();

        switch (m_ClearMode)
        {
            case ClearMode.All:
                // Clear color, depth and stencil render targets. Stencil is cleared with value 0xF0.
                buffer.ClearRenderTarget(RTClearFlags.All, Color.red, 1.0f, 0xF0);
                break;
            case ClearMode.ColorStencil:
                // Clear only color and stencil render targets. Stencil is cleared with value 0xF0.
                buffer.ClearRenderTarget((RTClearFlags)((int)RTClearFlags.Color | (int)RTClearFlags.Stencil), Color.green, 1.0f, 0xF0);
                break;
        }

        camera.AddCommandBuffer(CameraEvent.AfterSkybox, buffer);
    }
}
