- Percentage of beasts dead for stoppage - i'm assuming that this means history generation will stop early if this % of beasts die for any reason. please verify
I was under the assumption that this stops them from dying after a certain percentage?
It definitely stop worldgen early if it hits this %
- Min/Max Elevation - If I understand properly this does not actually impact the depth of the terrain, only the range of elevation levels available at the regional level. Please confirm/elaborate
You've got me, I've never messed with this and gotten a world to generate. Kept complaining that the world was too flat for mountains.
No variation give a (pretty much) flat world. The rejections can be turned off in other settings. A high minimum means no oceans, a low maximum means no mountains. I found rivers need a min. elevation of 300 for the start. Setting a world with elevation 299 everywhere affected river generation. Setting 300 everywhere was ok for rivers.
- Drainage - What does drainage do other than being required by certain biomes?
[if you make a lot of drainage, you can get a pretty nice lake. I got a big lake that looked almost like an ocean once, but the info assured me it was a lake.[/b]
Also seems to affect number/depth of soil layers i think.
EDIT : lower seems to give more soil, but I suspect other factors affect it too.
- Max number of subregions - What's a subregion and whats the practical impact of changing this?
Not sure what the impact would be, but see above for an attempt at describing them. Turning off subregions might actually be a good thing if you hate 200 Z level maps.
I always thought this is the number of separate biomes, eg the flashing regions you see on embark when you hit F1 and F2 when there's more than one biome on the embark location. Higher should make the regions smaller, thus more varied embarks.
- Allow Init Embark Options to Show Tunnels - What is this?
Never seen one myself, but I'm assuming it allows you to see where tunnels are. If there still is tunnels.
[/list]
Shows cave location in local area embark selection, same symbol as a stone in-game, create a world with many caves and almost every 16/x16 embark region can have one.
EDIT : I was wrong on the last one, tunnels not caves, as I see now. I never played 40d
