Although 360° Adjustment Layer 4D is part of an Alex4D effects package, it appears in the Titles browser:
360° Adjustment Layer 4D is a special title that can be used to modify all the clips below it in the timeline. Any effects applied to it are applied to all the video, stills and titles below it. First all the media below is combined into a single 360° clip, then any effects applied to 360° Adjustment Layer 4D are applied to this single clip.
For example, if you have a title and a few images that you want to have in four different directions, you could apply 360° Repeat Sphere 4D to each clip. Alternatively, you could add an instance of 360° Adjustment Layer 4D above the clips you want to repeat, and apply 360° Repeat Sphere 4D to the 360° Adjustment Layer 4D title.
