In this simple tutorial, I am going to explain how to make a ’’Fake Global’’ illumination (Fake GI) without using any 3rd party render which nearly is the same quality as using GI’s but less time consuming to render.
（在这篇简单的教程中，我将介绍如何模拟全局照明，这样即使不用第三方的渲染器，也能达到近似的效果，而且能节省渲染的时间．）
Ok, Change the selection ALL (see image below) into lights which will help the selection of light. Use the Move tool to move the lights. Gizmo X, Y, Z, to move the light to the precise position.
Then set the Direct as well to (0, 0) in X,Y,Z gizmo. After that drag it to X gizmo using move tool.
(同样把平行灯也移动到（0，0），然后拖动ｘ变换轴到如图位置。）
Select the light (the target and the direct*), then group it
(选择创建的灯（包括目标点和灯点），将它们成组。）
Go to Top Viewport, set the pivot this time to (0, 0) in Y gizmo. Make sure the affect pivot only is active. Then Deactivate after you finish setting it. (In Tab Hierarchy)
(转到顶视图，设置轴心点到（0，0）。请确认选择了“仅影响轴心点”按钮。完成后关闭这个按钮。（在历史面板）。）

Done. Set the group gizmo, then we copy the lights in instance using the Array tool. (Tools > Array) Settings refer to the image
(继续。选择灯光组，在阵列工具选择“关联”复制方式。（ｔｏｏｌｓ>ａｒｒａｙ）具体设置参照下图。）
Go to Top Viewport, select all the lights except the Target. (Ungroup all the lights first) The easier way is ungroup all the lights > CTRL + A> hold ALT + select all the Targets.
After doing this, select the Directs, copy it to Y gizmo and use instance copy. (Front Viewport) Then copy it again once more, scale it until it looks like the shape of a dome. For a better results, add 1 direct above the dome by select 1 direct copy instance and move it upward and set the Gizmo X & Y to (0,0).
