I build interactive projects for museums where the user is able to visit the same landscape but from different time periods. In UE4 I just loaded in a new level which had everything in it. For example, moving from a medieval landscape to an Iron Age landscape. It’d have the same terrain but all the Fauna & Flora, Props and NPCs would change to reflect the new time period. The huge landscapes I build use height maps.
Q: Is it possible to keep the landscape and swap its landscape material AND all the above Fauna & Flora, Props and NPCs in BPs? I’d like to, for example, swap all the fauna on a click of a button. Is that possible in UE5?
