I have been investigating the changes with 1.14 and have seen that you can now use intReferenceHolders in containers to really easily sync things like machine progress and energy storage across the client and server. So I am just wondering if there is any new way of easily syncing dynamic fluid tanks. Because you could obviously just sync the tanks current amount using the intReferenceHolder method if you knew it would always hold a certain type of fluid, however what about tanks that can hold any type of fluid. Is there an easy way to tell the client what type of fluid is in the tank?

So the fluid system hasn't been ported over so this won't be achievable right now. But I guess my question still stands for the future unless it's possible that the rewrite will offer a way of doing this.
