The Rules of Animation Tracks

When iClone is playing a project it will follow a specific priority as it encounters multiple clips or keys in the same frame. The priority of the tracks for actors or iProps is as follows (from highest to lowest):

Priority	Animation Tracks	Source of Motion
1	Motion Layer and Transform tracks.	Motion Layer keys are generated by users' custom motion editing from Edit Motion Layer Each time you adjust the actors' Transform data, a key will generate in the Transform track.
2	Operate tracks.	Operate tracks keep the actors' motion when interact with iProps
3	Perform tracks.	Perform tracks keep the motion applied directly from the content library in Editor Mode or generated from the Director Mode perform commands, e.g. hotkey 1,2,3,4.
4	Move tracks.	Move tracks keep movement animation generated from Move commands, e.g. WASD walk and run motions in the Director Mode or right-click menu command.
5	Idle tracks.	Idle motion is automatically generated when you playback the project, the longer you play, the longer the idle motion clips are randomly generated. You can turn off the idle motion generation by check off Persona - Auto Add Idle Motion If any given time there is no other motion track data exists, idle motion will take place. Idle motion clips and random probabilities are defined in Persona AML file.

Note:

Please note that although clips in the Perform track possess higher priority than ones in the Move track, all the Perform clips that are applied from the Content Manager/Template or Custom libraries will have lower priority than the ones in the Move track.
The priority of Move and Perform tracks can be defined by DramaScript AML file, it means you can have your actor walk, in the same time perform fight or smoke on the upper body part.
