Pedestrians can appear in different times at different places (unlike idlers, who remain in place for the entire simulation). Each animation of a pedestrian, from the time it enters a portal to the time it exits a portal, is a spawn.
For example, when the lady with the purple shirt exits a flow, she might later enter elsewhere.
There are five operations you can perform on selected pedestrians: regenerate, swap appearance, switch resolution, delete, and bake. When performed on a pedestrian with multiple spawns, some of these operations affect only the current spawn—the one which is active at the current frame—and others affect all spawns of the selected pedestrian. Here is a table that shows how each operation works:
| Operation | What it does |
|---|---|
| Regenerate | Affects only the current spawn. |
| Swap Appearance | Affects all spawns. |
| Switch Resolution | Affects all spawns. |
| Delete | Affects only the current spawn. |
| Bake | Affects all spawns. |
