These rollouts, available when a Populate flow, idle area, or seat is selected, enable setting parameters such as the number and distribution of people, gender ratio, and more.
After changing any of these settings, click Simulate to see the results.
Note: Baking characters does not trigger re-simulation. Once a character has been baked, you must unlock the Z scale in the Link Info menu to have the character scale correctly when you scale the idle area.
