They carry over everything you see on the generate map screen.

Yep, just tested it, it works even for all the advanced settings (biter expansion and stuff). That's cool.
TIL.

This is what the map exchange string is. Literally - it copies all settings in that display and restores them when pasting it into the exchange string field.

Does the map exchange string include the world seed?

Yes, it does.

Yep.

Funny and slightly... stupid at the same time.

WARNING: Editing the base.cfg file turns out to cause problems joining multiplayer games. Apparently the contents of this file are compared, and once I edited the file I can't join multiplayer games because "mods" version is different. So only do this if you're OK with just single player.

I was also able to create my own custom preset. I'm not a programmer or anything and it took some trial and error, but by editing two of the configuration files with Notepad++ I got it to work, including fixing the "weird name".

As bagaznal described, I edited the \Steam\steamapps\common\Factorio\data\base\prototypes\map-gen-presets.lua file. I copied and pasted the Rail world section, as this most closely matched what I was after. By changing the values and adding a few others (based on examples from other sections), I got that file to "set" the resources and water how I wanted it. It took me a few tries to get the hang of the syntax, the commas mostly, but after 10 minutes and a half dozen attempts, I got it to work.

But it was still giving me the funny name thing. I poked around a bit and discovered the Descriptions for each preset type in the following file:

\Steam\steamapps\common\Factorio\data\base\locale\en\base.cfg

This is the locale version for English, so if you play with a different locale, find the one appropriate to your locale.

There are two pretty obvious sections to edit here in the base.cfg file; [map-gen-preset-name] and [map-gen-preset-description]. Type in the exact preset name you called your custom preset in the other file, and then give it a friendly name. Type a description of it as well. When you're in there, it's pretty obvious as to what you need to do.

I'll attach my edited files. I did a custom preset with very rare frequency resources, but with very-high richness and very-large size. It also has large bodies of water to get some diversity and variety.

It's really annoying to always re-select like 20 parameters.
A quick and dirty solution would be to allow changing the preset-file without conflicts in multiplayer (different base-mod).
Would be good enough for now. Some fency GUI can be added later on.

I'm really missing the ability to save new presets for creating a new world. It takes a lot of time to change everything, especially if experimenting with the world gen, and it would be nice to not have to write down or just remember what the good settings we find are.

Hello!

I would like to have an option to save my setting values into a custom preset to have on the list with add/remove custom presets.

Also I would like to have an option to manually select spawn location once you generated the map preview.

+1 to save presets. Pretty annoying to redo them

+1 to save presets. Very annoying to put settings back in each time. I would like to have a saved preset for peaceful mode, one for my version of rail world, one for my version of default, etc

+1479 to saving/loading map generation numbers!
Why 1479?
Because that's how many days it's been that this idea has been requested and not implemented! ^^;

I'd love to see it where we could define and add our own custom presets to the map generator. A lot of times, I find myself making the same set of changes to get a new map started. But rather than having to redo these every time, a preset would be a much nicer solution. They could be accessed in the same drop down as the current eight presets the game comes with.

save the map exchange string (can also be exported from save files, so you dont have to save it external), import it in the new map.
You can still reroll terrain generated, map settings will stay the same


but I +1 this, given how often people start new maps

I would like this very much for all the reasons you gave.

I could be remembering things incorrectly (it's been months since I recall reading that) but I believe that the seed you use is actually the spawn location. From what I recall reading awhile back though, the overall world is actually the same regardless of the seed. Seed just sets where you spawn in the world.
