When building an Xbox One Streaming Install package (makepkg.exe) The layout generation code in Unity will assign each Scene and associated assets to individual chunks. Unity will mark Scene 0 as being part of the launch range, IE the set of chunks required to launch the game, you may include additional Scenes in this launch range if you desire, this specifies a range of Scenes (starting at 0) to be included in the launch set.
（注意：如果用户使用他们自己的布局文件，则此选项毫无意义，使用自定义布局文件才是处理更高级打包要求的正确方法）。
