How to join 2 FNames without converting it all into strings?
This post should help you
The only workaround for joining FNames was to convert to a FString, do my concatenations, then convert back again.
Dumb. Me or FName?
In general, FNames are usually something you aren’t stringing together dynamically. What a re you using this dynamically built FName for?
just to get names dynamically of level to load
LEV_001, LEV_002, LEV_003 …
The built in UE static uses an FName for the level reference…so I built my concatenate function using FNames…well bad idea!
I don’t think you want to be using or operating on FNames until you absolutely need them.
