If you have several objects in a scene that you want to appear or disappear with equal intervals, DISE Composer has a nice feature that lets you distribute the objects in time.
The feature can be found on the edit menu under Edit > Distribute > Timing
Let us say that you have four text rows that you want to appear with an even interval between each text row.
There are 3 more distribute time functions that all work in a similar way:
Distributes the times the objects disappear instead of the time they appear.
Distributes both the times the objects appear and the time they disappear independent of each other.
(In this example, we shortened the display time of the text “example” before distributing to clarify the function)
This also distributes both the times the objects appear and the time they disappear, but every object will be the same length as the first one, so they will disappear by exactly the same timing as they appear.
