Private Planet ReBuild Option

By terrain do you mean the top layer of clay/peaty/silty that covers the world? Or are you talking about the actual shape of the mountains and hills and valleys, etc.?

For the former, yes this is possible. Keep the seed the same and change the strata config and you can get a hill that was covered in silty covered in peaty.

For the latter no. That’s the entire point of the seed, to control the randomization. If you use the same seed within the various noises the noise randomization will always been the same.

If you open up world builder (or check out my video series) you can see that they actually do some really cool things with this within the different dev-provided configs. This post of mine kind is a “basic” example that took me a hot minute to figure out :rofl:
