For presentation purposes, a smooth transition is applied when switching between
position, human, and viewpoint variants (also known as animated variants). You can specify
this length for each animated variant.
Note:
In the preferences, you can also define a default length for this transition (as well as
other timing options). For more information, see Presentation (Play) Mode.
Click the menu of the variant thumbnail and select Animation
Duration.
Specify the length of the transition (in seconds).
