Multiplayer

The Foliage Plugin is server authoritative and works on both listen servers and dedicated servers.

Damage must be applied on the server

Foliage instances and Foliage Actors only react to damage on the server. Damage applied on a client is ignored. Send a Server RPC from the client, and apply the damage from there:

Client: Input → Server RPC "Harvest"  →  Server: Line Trace → Apply Point Damage

The Foliage Plugin Interface events also run on the server.

What is replicated

What	How
Hidden and removed instances	Sent to every client when they change.
Instances changed before a player joined	Sent to the player in chunks once their world has loaded.
Foliage Actors	Normal replicated Actors. Mesh, remaining uses and depletion are replicated.
Physics movement of depleted actors	Only when Replicate Physics Movement is on. See below.

The Foliage Manager that keeps track of the instances is spawned automatically on the server and is always relevant. You never place it in the level yourself. See Custom Foliage Manager if you want to extend it.

Events on clients

Event	Server	Clients
BPE On Foliage Damaged	✓
BPE On Foliage Remaining Uses Updated	✓	✓
BPE On Foliage Mesh Updated	✓	✓
BPE On Foliage Depleted	✓	✓
On Foliage Harvested / On Foliage Error Message	✓

Play effects and sounds from the replicated events, and gameplay logic from the server-only ones.

Physics movement

Replicate Physics Movement in the Plugin Settings is off by default to save bandwidth. Each machine then simulates a falling tree on its own, so the end positions can differ slightly. Turn it on only if the position of depleted actors matters for gameplay.
