Hello Devforum, I haven’t made a scripting support post in a while but I decided to rewrite my voxel terrain generator but I’m having some issues currently.
I have never used region3 before and Terrain:WriteVoxels() and I’m running in some issues.
I am running command
require(game.ReplicatedStorage.rubysvoxelworldgen.chunkmod).loadchunk(workspace.CurrentCamera.CFrame.Position)
in the command bar to test a chunk loading function,
but I keep getting this error.

It keeps telling me regions can’t be empty and such but I am pretty sure they aren’t empty, first time using region3 tbh so I’m uncertain, but I also don’t know where the issue is at.
I feel like maybe at where I am trying to set the start position offset or so for the chunk to load (this is so when you load a chunk the “center” of the chunk isn’t at the corner), but again I am very unsure about that.
My previous terrain generator just spams the FillBlock() function of terrain and I want a terrain generator that generates more beautiful and costs less performance, figured out I had to use WriteVoxels() for that assuming that’s faster than just spamming the FillBlock() function in a loop, it also has the advantage of being able to generate caves and more impressive mountains, overhangs, etc, it made my script spike to 90% activity and heats up my computer since it’s supposed to generate a infinite world in run time so you can explore for yourself.
