Game seeds and planet size

[VulcanTourist]

How does planet size affect the terrain generation result of game seeds?

POIs are pretty sparse on Very Large planets. I make changes to the yaml file to get more stuff.

I'm curious how the planet size affects terrain generation produced by a particular seed, not the POIs. I doubt the difference is as simple as a scaled-up or -down version of the same random features.

The planet size makes a huge difference in the look of the planet. I just compared seed 201067 in the medium and the large planet versions and it didn't look like the same planet.

The differences were obvious even in the map view, then?

Both these screenshots are from the same seed, but the upper one is from a medium planet and the lower one is from a large planet.

There was a lot more water on the small planet.

It seems like the terrain is generally the same. Water will be in about the same spot, a high mountain peak, open plains, things are just adjusted to fit.

I'm particularly wondering how similar the terrain features are planet-wide. Are close to identical forms visible in both? It would make sense that there appeared to be more water on the smaller planet if an absolute value was used instead of a proportional one.

I want to explore this when it's time for a new game.

Off my own topic somewhat, I'm impressed by the variety of forms I see now. Just minutes ago I came across a deep winding chasm, of the sort you might see in a ship or aircraft chase scene. The biome transitions are quite unexpected now; I saw a tiny beach biome barely big enough to fit an SV tucked away down in a deep depression in a mountain range.

Similar-ish in my testing.

There was one particular mountain range on the large planet which I was able to find on Medium and small planets. It was in pretty much the same spot for each planet size. On all planets it was almost completely verticle on one side. The number of peaks, spacing of those peaks, and overall size of that particular range was different though.

I was interested in checking it out too. Here's what i found:

As a player starting each game, I felt like the planets were a lot "different".
I'm going to see if I can line up the global maps better, I think they are taken from different areas.

You can preview the same planet with different sizes or seeds in the SSG.

Gave you got that yaml file? I probably won't actually use it directly, but instead as a reference for a working one (it's so easy to break a yaml file).
