如何在自定义过程中渲染基本的GameObject(Unity:ScriptableRenderPass)?

我想做的事情: 在我的自定义过程中渲染特定层的游戏对象。我稍后想做更多的事情,但我只是想让它像URP一样渲染。

我只是在学习ScriptableRenderPass/ScriptableRenderFeature,所以我开始学习基础。

以下是我想要的:

以下是我得到的:

这就是我的传球执行的样子:

    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);
    }

看起来它的轮换(因此,它的MVP矩阵)是正确的。。。但它没有照明。我不知道第二个黑暗立方体是关于什么的。因此:

选项#1) 弄清楚我需要向命令缓冲区传递哪些命令才能应用照明。。。并修复黑暗方块的任何内容。。。希望当我开始绘制更复杂的着色器时就是这样。

但后来我有了一个想法:

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”。

以下是我得到的,无论我试图用这种方法做什么:

(我知道我本可以什么都不说……但是…)

为了开始这种方法,我只是想传球,吸引一切。但我可以用它画任何东西。为什么?
