What Are All Requirments For Forming Rivers?
« on: December 31, 2020, 10:48:44 pm »
I'm making a world without mountains and can't get past river forming stage.

I was modifying other values related to it, except temperature. Only forests can exist in my world. Drainage is only 33 and rains are 74-75.

My settings are:

Elevation 100-299 (no oceans/mountains)

Erosion Cycle Count: 0

Minimum/Desired River Start Locations: 0

Periodically Erode Extreme Cliffs: Yes

Do Orographic Precipitation and Rain Shadows: Yes

Setting a world to generate non-forest hill areas doesn't work. I already nulled all minimal amounts of regions to be generated. Now only forests have minimums.

I'm playing newest version of the game.

Well, your experiement leans towards a very obvious answer...
Try twice more more, all vanilla except elevation. Once with oceans and no mountains then again with mountains and no oceans. Then post your results.

Also, what happens when you increase Minimum River Start Locations? Endless worldgen loop?

Minimum rivers affect how many of them must exist, otherwise rejection.

I had returned them to default but nothing happens.

I just read on wiki they need 300 elevation to form up.

Hey! I just figured out that rivers need drainage under 33 to form up. Looks like I need to allow swamps.

Is this world for Fortress mode, or Adventure mode?

The reason I ask is.. unless you have at least one 300+ elevation location, a dwarven civ cannot be placed, and so worldgen won't proceed if you have playable civ enabled and one civ enabled.

Setting that aside, you can have as many surface water features as you wish, or not, pretty much on demand in whatever location(s), with great flexibility and options.
The size of the surface water feature (spring, brook, stream, minor river, river, major river, waterfall) can of course vary drastically based on a bunch of factors.

What are all the needs for mandatory dwarven civilization? My world has all medium and large subregions evil and all small ones neutral. There is 65 savagery everywhere (1 point away from high level). Is this maybe because everywhere temperature is 90? There are mountains of course that are neutral. Rainfall and drainage are 0 everywhere.

BTW How are first werebeasts made? Only by being cursed by gods?

A non savage, neutral (non evil/good), 300+ elevation, produced either via volcano elevation, or specific mountain biome generation.  And a wet cavern, for crops.
You also need at least 4 Z levels of elevation disparity somewhere in the world for rivers to form. 
If the entire world is one elevation (100 for example) then you get no rivers.  If one tile is 104, and the rest are 100, you'll get rivers.
Here's an example of a worldgen that will produce worlds filled with brooks, streams, and rivers that has no explicit 300+ elevation, but that elevation is achieved via volcanoes in the NW corner of a pocket world, so the dwarven civ always gets placed there.
