you need to send a trigger (variable, skill or so) to the clients, they need to ask if this trigger is set, and activate the function again local by their own.

like:
server creates model -> server set trigger -> send var to all clients -> client get trigger -> client create model


when a client creates the model, the client needs to send the trigger to the server:
client creates model -> sets trigger -> send var to server -> server creates model -> server set trigger -> send var to all clients -> client get trigger -> client create model (except the start client)
