**我尝试做的是：**渲染特定图层的游戏对象（S）在我的自定义通道中渲染。我想做更多的事情后，但我只是想让它呈现完全一样的URP会现在。

我正在学习ScriptableRenderPass/ScriptableRendererFeature，所以我开始使用基本的。
我想要的是

我得到的是

这是我的pass的Execute看起来的样子：

public override void Execute(ScriptableRenderContext context, ref RenderingData renderingData)
    {
        CommandBuffer cmd = CommandBufferPool.Get("EnemyClearDepthPass"); // Take this outside if you don't need this to change at all.

        foreach (var renderer in _associatedObjects)
        {
            if (renderer.isVisible)
            {
                cmd.DrawRenderer(renderer, renderer.sharedMaterial);
            }
        }

        context.ExecuteCommandBuffer(cmd);
        CommandBufferPool.Release(cmd);
    }

看起来它的旋转（因此，它的MVP矩阵）是正确的……但没有灯光我不知道第二个黑暗方块是什么。所以：

**选项#1）**找出我需要传递到命令缓冲区的命令，以便应用照明...解决黑暗方块的问题希望我开始画更复杂的着色器的时候就是这样。

但后来我有个想法：

**选项#2）**也许我可以使用ScriptableRenderContext.DrawRenderers（...）来绘制它，因为我认为它会更“开箱即用”。

这就是我得到的，无论我尝试用这种方法做什么：

（我知道我可以什么都不说……）但是......）
为了开始这种方法，我只是想做一个吸引一切的传球。但我可以让它画任何东西。为什么？
