## Verified notes

### Two players on one horse

A player who climbs onto another player's horse as passenger is dismounted after about 3 seconds, with a clean dismount animation (no ragdoll, no buck, no change of network owner). Spawn flags, mount ownership (`SET_PLAYER_OWNS_MOUNT`), `SET_ANIMAL_IS_WILD` and PLAYER↔PLAYER relationships make no difference.

The cause is RDR's companion rule: the passenger must be in the rider's ped group. Ped groups are local, so add each other on **both** clients:

```lua
-- on every client, for the other player's ped that shares your mount
SetPedAsGroupMember(otherPed, GetPlayerGroup(PlayerId()))

-- when they get off
RemovePedFromGroup(otherPed)
```

Wagons and carts do not need this. There is no `SET_PED_NEVER_LEAVES_GROUP` in RDR3.

Verified in game on the Borderline RP server, September 2026.
