Spawn a vehicle
Vehicles come out of the same panel as NPCs.
In the menus: ESC → Design → NPCs → SPAWN NPC...
Spawn a vehicle from the panel
Change Kind: from NPC to Vehicle.
StoryForce ships no vehicles of its own, so everything in the list comes from the base game or from whatever is installed on the server. Use Find: and SEARCH to narrow a long one.
Pick a row and drag the preview to turn or tilt it. Select SPAWN NOW. The panel stays open.
Where the vehicle lands
There is no ghost, so you aim a vehicle by standing where you want it. It drops roughly 64 units in front of you, facing away, and is lifted clear of the floor for you.
Carry passengers
Seat NPCs in vehicles explains RIDE and DISMOUNT on the GROUPS panel.
Piloted speeders and animals can take passengers when they have a free configured seat. The vehicle model also needs matching passenger attachment points for riders to sit in the right place.
Ride as a vehicle passenger covers boarding, looking around and getting off.
