Hello,
Arma have a problem of synchronization of damage on all object that have damage = tree / fence / bush / wall in named properties. This only happen when you bring it down with a vehicle.
When you are killing a tree with a vehicle in arma, this will tilt the tree. In multiplayer this synchronize for JIP player.
But I have a problem when restoring the damage on the tree. If I restore the damage, all players in the actual session will see the restored tree, but if a JIP player will connect, he will not see this restored tree, but if I check the damage on tree with damage command, this will return 0.
So we have just a problem of the synchronization of the tilted animation and not the damage itself synchronization.
