This is the place for those troubled individuals who are attempting Advanced world generation but end up with nothing but rejections from the world generation process.

For general information about advanced world generation, see Advanced world generation.

Solving World Rejection Problems

Generally speaking, you can always solve world rejection problems by nullifying (setting to 0) all of the parameters that specify "minimum number of" whatever. The main problem with this is that many of the details of your world will be left purely to chance, perhaps not giving you the sort of conditions that you're looking for.

One general thing to try is nullify all of the parameters that cause rejection (most of which contain the word "minimum") and see what is generated. If you find that you get too few mountains, for example, you can then play with parameters such as elevation and see what happens. This will give you a chance to actually view the worlds that would otherwise be rejected so you can get a better idea of what impact various settings are having.

The Rejection Log

Change the Init file from [LOG_MAP_REJECTS:NO] to [LOG_MAP_REJECTS:YES] and in the main Dwarf Fortress folder you'll find a file called map_rejection_log.txt. Every time a world is rejected the reason will be logged to this file. Reading this file will give you a better idea of what is going on than the "having trouble placing" errors that you get on the screen only after a few hundred errors, not all of which may be the same as the specific "having trouble placing" dialogue that is shown.

Reasons

LACK OF PEAKS

The world generator is having trouble placing enough mountain peaks.

If you are using custom presets:

You might want to check your preset elevations for the elevation 400.

You must have at least as many of these highest elevation points as you are requiring peaks.

Otherwise:

You might want to check your maximum elevation value and other elevation parameters.

Alternatively, you can reduce the number of peaks required by the parameters.

Log message:

• Not enough peaks

MEDIUM ELEVATION REJECTION

You might want to adjust the parameters governing elevation frequencies.

Alternatively, you can reduce the number of mid-level elevation squares required.

Log messages:

• Not enough medium altitudes
• Not enough medium altitudes after shift down
• Not enough medium altitudes after shift up
• Not enough medium altitude locations after erosion

LOW ELEVATION REJECTION

The world generator is having trouble placing enough low elevations.

TUNDRA REJECTION

If you are using custom presets:

You might want to check your preset volcanism for the value 100.

You must have at least as many of these highest volcanism points as you are requiring volcanos.

Otherwise:

You might want to check your maximum volcanism value.

Can volcanism be placed at the value 100 enough times to provide space for each of your volcanos?

Alternatively, you can reduce the number of volcanos required by the parameters.

Log message:

• Not enough volcanos

LACK OF RIVERS

Make sure your parameters and presets allow as many mountain squares as you are requiring river start points.

Alternatively, you can reduce the number of rivers required by the parameters.

Log messages:

• Not enough river start points before erosion
• Not enough river start points after erosion

TOO MANY REGIONS

The world generator is placing too many subregions.

Make sure your parameters and presets aren't so variable that biomes change frequently.

Alternatively, you can increase the number of subregions permitted by the parameters, up to the cap.

Log message:

• Too many distinct subregions (over by #)

LACK OF MOUNTAIN CAVES

The world generator is having trouble placing mountain caves.

Make sure your parameters and presets allow as many border mountain squares as you are requiring mountain caves.

Alternatively, you can reduce the number of mountain caves required by the parameters.

Log messages:

• Not enough mountain cave locations
• Not enough mountain cave locations after location check

LACK OF LOW-LYING CAVES

The world generator is having trouble placing low-lying caves.

Make sure your parameters and presets allow as many mid-elevation squares as you are requiring low-lying caves.

Alternatively, you can reduce the number of non-mountain caves required by the parameters.

Log messages:

• Not enough low-lying cave locations
• Not enough low-lying cave locations after location check

UNABLE TO PLACE ENOUGH CIVILIZATIONS

The world generator is having trouble placing enough civilizations.

Make sure your parameters and presets offer enough low-to-mid savagery, evil/good appropriate, biome appropriate squares to establish sites.

High savagery (66+) blocks civilization placement -- make sure your parameters and presets offer at least small pockets of low-to-mid savagery areas.

If you have very few biome types and are placing good or evil regions, they\'ll often crowd out the civilizations as well.

Alternatively, you can reduce the number of civilizations required by the parameters.

Log message:

• Not enough entity placement locations

NO CIVILIZATIONS AVAILABLE

The world generator is (sic) couldn't find any civilization definitions.

This problem cannot be resolved by continuing, so you should either abort or skip all rejects for a legends-only game.

Log message:

• No entity definitions available

UNABLE TO PLACE CONTROLLABLE CIVILIZATION

The world generator is having trouble placing a controllable civilization.

Dwarves, for example, require non-evil, non-good, unsavage mountain squares that aren\'t surrounded by the ocean.

Make sure your parameters and presets have adequate squares of this kind.

Alternatively, you can remove the requirement of a controllable civilization from the parameters, which will restrict you to adventurers (assuming an appropriate civilization is placed).

Log messages:

• No controllable entity definitions available
• Did not place controllable entity

Error Continuation Options

Note: If you are using the default parameters in unmodded DF, and it doesn't work after continuing a few times, please report the issue at the B12 forum.

• CONTINUE until you give me another warning.
• ABORT NOW and I'll look over my parameters.
• ALLOW THIS REJECTION TYPE and continue reporting others.
• ALLOW ALL REJECTS, even if I end up with a legends-only world!
