Here is a tutorial video for replication of instant swimmable water. The real reason the asset “mirrors animations and sfx” is because he used the get physics volume node which returns the world default physics volume if your not in a physics volume. It would be great if you could add physics volumes to an actor class BP. Clients are all in the servers default physics volume or the settings are replicated from server not positive which. Therefore when it sets the default physics volume’s boolean variable “water volume” to true on server, everyone is now in a water volume. There is many other reasons this asset wasn’t mp ready but I feel this was the main reason it was mirroring animations.
