In my case, I have 1 animator with many layers. Each layer has an animation. How can I connect these animations together? I want to play these animation by a custom order which is made by user. For example, I have 3 animations 'wave', 'clap' and 'walk'. I want my user can make 3 animations into 1 united animation. These new animation will start from 'walk' then 'wave' then 'clap'. How can I do this? Thanks.
