You have created various Entity Types and you wish to play the exact same behaviors on each of them.
Please refer to this documentation page to know how to Share a Behavior Container between multiple Entity Types.
The most simplistic way to play multiple motions on a single entityType is loading your motions under a single Motion Behavior (as seen in Create a random motion loop).
For more control over the ratio of used motions, use the Random Operator .
When using a Random Operator to play multiple motions on a single entityType it may be interesting to edit the rate of characters playing a motion instead of another.
With the default values of 1 and 1 the motions are played 50/50.
Just go inside the Random Operator attributes and edit the weight of your Behaviors
One motion is played by 100% of the entities.
One motion played by 80% of the crowd.
For even greater control and being able to go from one random motions to another, see Switching From One Motion Loop to Another
