# Customizing Ultra Space in Pixelmon

Customize how Ultra Space works on your Pixelmon server with the settings in ultra_space.yml. This guide explains how to configure wormholes, dimension-specific spawning, level scaling, environmental hazards, and other mechanics unique to Ultra Space.

The Ultra Space section contains the options Pixelmon uses for this part of the server. Configure Ultra Space rules, wormholes, levels, hazards, and dimension-specific spawning behavior.

## Pixelmon Ultra Space Settings

The settings below are listed in the same order as they appear in ultra\_space.yml. The table preserves each default and identifies the accepted value type. The Setting column shows a reader-friendly name first, followed by the matching ultra\_space.yml key for reference.

| Setting and Config Key | Default and Accepted Values | Description |
| --- | --- | --- |
| **Ultra Space Shiny Rate Multiplier** ultra-space-shiny-rate-multiplier | **Default:** 0.5 **Values:** decimal number | Modifies the rarity of shiny Pokémon in the Ultra Space Dimension (shinyRate * ultraSpaceShinyModifier). |
| **Ultra Space Hidden Ability Multiplier** ultra-space-hidden-ability-multiplier | **Default:** 0.5 **Values:** decimal number | Modifies the rarity of hidden abilities in the Ultra Space Dimension (hiddenAbilitySpawnRate * ultraSpaceHiddenAbilityModifier). |
| **Ultra Space Horde Spawn Rate** ultra-space-horde-spawn-rate | **Default:** 0.4000000059604645 **Values:** decimal number | Modifies the rarity of horde battles in the Ultra Space. |
| **Spawn Levels Increase In Ultra Space** spawn-levels-increase-in-ultra-space | **Default:** true **Values:** true or false | If enabled, the Ultra Space Pokémon will be set at a higher level than the maximum level in your party MaxPartyLevel * ultra-space-level-multiplier |
| **Ultra Space Level Multiplier** ultra-space-level-multiplier | **Default:** 2.0 **Values:** decimal number | The maximum level multiplier when you're in Ultra Space. |
| **Ultra Space Gigantamax Factor Modifier** ultra-space-gigantamax-factor-modifier | **Default:** -1.0 **Values:** decimal number | Modifies the rarity of the Gigantamax Factor in the Ultra Space Dimension (gigantamaxFactorSpawnRate * ultraSpaceGigantamaxFactorModifier). -1 disables Gigantamax Factor spawns in Ultra Space. |

## Important Ultra Space Setting Notes

### Defaults and Value Types

Boolean toggles, numeric rates, timers, lists, and mappings use different value formats. Preserve the value type shown in the table and keep collection syntax intact when changing ultra\_space.yml.

### Settings That Work Together

Several ultra space options can affect the same outcome. Review related rates, limits, timers, and lists together before deciding that one value is responsible for a result.

### Testing Changes

- Change one related group of settings at a time so its effect is easy to measure.
- Test the result under the conditions affected by the setting, including relevant dimensions, player states, or encounter types.
- Keep a copy of the previous values so unexpected balance or performance changes can be reversed quickly.

## Final Thoughts

Ultra Space settings are easier to balance when changes are deliberate and documented. Start with the defaults, adjust only what the server needs, and verify the result before moving on to the next group.
