The direction will depend on the emitter shape.
| Emitter Shape | Direction |
|---|---|
| Point | Same as LocalNorth. |
| Disk | Same as LocalNorth. |
| Rectangle | Same as LocalNorth. |
| Sphere | The direction cannot be changed for this emitter shape. |
| Box | If emitInside is true, it picks a direction parallel to a random local axis. If it is false, the direction will be out from the box, perpendicular to the side where the particle was emitted. |
| Cylinder | Out from the cylinder's axis. |
Global up. (+Y)
Global down. (-Y)
Global north. (+Z)
Local up. (+Y)
Local down. (-Y)
Local north. (+Z)
An emitted instance's initial direction is used for various things that require a direction, but does not have a set one to follow.
The initial direction can be further modified by the following actions:
