详细说明

当禁用时，NoPicking 节点不会阻止拾取操作的执行。因此，切换 enabled 属性是使 NoPicking 节点生效或失效的一种方式。

在 FrameGraph 中使用多个子视口时，NoPicking 可用于防止重叠视口或非可视视口之间的拾取冲突。它还可以作为一种优化手段，避免为隐藏视口或场景中无需进行拾取操作的部分执行不必要的工作。

Viewport {
    CameraSelector {
        NoPicking {
            ClearBuffers {
                buffers: ClearBuffers.ColorDepthBuffer
                NoDraw { } // Prevents from drawing anything
            }
            RenderPassFilter {
                ...
            }
            RenderPassFilter {
                ...
            }
        }
    }
}
