Client-side configuration controls visual effects, particle systems, and UI preferences that only affect your local game client. These settings do not require server synchronization and can be changed without affecting other players.

​
Configuration file

Client options are stored in: 
config/regions_unexplored-client.toml
Most client configuration changes require a game restart to take effect.

​
General client options

​
Particle effects

Control particle effects added by the mod:

​
Block color options

Customize color properties for specific blocks with dynamic coloring:

​
Eucalyptus tree colors

Eucalyptus trees feature a unique gradient color system that transitions across biomes and coordinates. These settings control how those colors appear:

​
Configuration examples

config/regions_unexplored-client.toml
[client_options]
CUSTOM_ITEMS_IN_VANILLA_CREATIVE_TABS = true

[particles]
# Disable particle effects for better performance
LEAVES_PARTICLES = false
PRISMARITE_SPARKLE_RATE = 0.0

[block_color_options]
# Keep default color settings
EUCALYPTUS_TRANSITION_SIZE = 25.0
EUCALYPTUS_SATURATION = 0.5
EUCALYPTUS_BRIGHTNESS = 0.8

Visual guide

Particle effects

Leaf particles and prismarite sparkles add ambient atmosphere to biomes. Adjust rates based on your performance needs and visual preferences.

Eucalyptus colors

The color system uses HSV (Hue, Saturation, Value/Brightness) to create dynamic gradients. Experiment with different combinations to find your preferred aesthetic.

​
Performance impact

Particle effects have moderate performance impact:
  • LEAVES_PARTICLES: Low impact - adds ambient particles near leaves
  • PRISMARITE_SPARKLE_RATE: Impact scales with value:
    • 0.0-1.0: Minimal impact
    • 1.0-3.0: Low to moderate impact
    • 3.0-5.0: Moderate impact in areas with many prismarite blocks
If experiencing low FPS in biomes with these features, try reducing or disabling these settings.
Color customization options have negligible performance impact. These settings only change color calculations which are very lightweight.Feel free to experiment with any values without worrying about performance.

Tips for customization

1

Start with defaults

Before making changes, play with the default settings to understand the baseline visual experience.
2

Adjust one category at a time

Change particle settings first, then color options. This makes it easier to identify which changes you prefer.
3

Visit relevant biomes

Test changes in the biomes they affect:
  • Eucalyptus colors: Visit Eucalyptus Forest biome
  • Prismarite sparkles: Explore Prismachasm caves
  • Leaf particles: Check various forest biomes
4

Consider shader compatibility

If using shader packs, particle effects and colors may appear differently. Test your configuration with shaders enabled if you use them.
Changes to client configuration require a full game restart. Use /reload or F3+T (resource pack reload) will not apply configuration changes.
