PasteRegion does not work on the client

  1. In my game, I have pre-build terrain with parts that acts as a region3 to use Terrain:CopyRegion() on then all the terrain is cleared. I want to allow clients to load these chunks in as they load in a different level/hub world. I tested it on the server and I got what I wanted to achieve, but the TerrainRegion data didn’t replicate to the client when using PasteRegion() After some research, I assume that using CopyRegion on the server then having the client paste it wouldn’t work, but then I saw another post saying it does replicate like that. I played it safe and just made the client use CopyRegion, clear the terrain and put the TerrainRegions in a folder in ReplicatedStorage. Alas, it did not work still. Documentation on Terrain functions are not very well written and I am stumped on what’s wrong with my code.

Notes:

  • I had replication issues before in a different game by turning off CharacterAutoLoads and i don’t know if thats affecting me again with this game
