人物和摄像机之间存在例如墙壁等的阻挡时  可以修改阻挡材质的alpha呈现半透明状 

 

using UnityEngine;
using System.Collections;
 
public class example : MonoBehaviour {
    void Update() {
        RaycastHit[] hits;
        hits = Physics.RaycastAll(transform.position, transform.forward, 100.0F);
        int i = 0;
        while (i < hits.Length) {
            RaycastHit hit = hits[i];
            Renderer renderer = hit.collider.renderer;
            if (renderer) {
                renderer.material.shader = Shader.Find("Transparent/Diffuse");
                renderer.material.color = new Color(renderer.material.color.r,
                                                               renderer.material.color.g,
                                                               renderer.material.color.b,
                                                               0.3F);
            }
            i++;
        }
    }
}                               

 

 

 

也可以像火炬之光那样  显示人物的透视效果

 

 

绘制被遮挡部分 ZTest Off，  ZTest Greater

绘制未被遮挡部分 ZTest On， ZTest LEqual

效果
