using UnityEngine;
using UnityEngine.UI;

public class Test:MonoBehaviour{
	
	public RawImage rawImage;
	public Camera cam;

	private RenderTexture m_renderTexture;
	
	private void Start(){
		m_renderTexture=new RenderTexture(512,512,16,RenderTextureFormat.ARGB32);

		rawImage.texture=m_renderTexture;
		cam.targetTexture=m_renderTexture;
		//必须为 CameraClearFlags.SolidColor或CameraClearFlags.Depth，CameraClearFlags.Nothing 时会不显示
		cam.clearFlags=CameraClearFlags.SolidColor;
		
		//CameraClearFlags.SolidColor时会有背景色，需要设置背景色透明
		Color color=cam.backgroundColor;
		color.a=0f;
		cam.backgroundColor=color;
	}
}

注意：Camera.clearFlags 必须为 CameraClearFlags.SolidColor或CameraClearFlags.Depth，CameraClearFlags.Nothing 时会不显示
CameraClearFlags.SolidColor：会有背景色，需要设置Camera背景色为透明
CameraClearFlags.Depth：不会清除上一次渲染的内容，会出现重叠花屏
