Building system replication

I have made a simple building system using blueprints and i managed to replicate buildings from server to clients (if server places those buildings), i used events on server and then multicast to clients. But i ran into a problem - i cant find a way to replicate buildings from clients to server (when client places a building server can’t see it), i hope someone could help me.

P.S Sorry for my bad english

Use Run on Server event… clients comunicating with server only(afaik) through this call…

This is my setup.

Close, but the server can’t know where you placed the building (I assume the building placement actor isn’t replicated right?). You need to send the transform yourself.
