JMtoXaero

JMtoXaero is a tool to convert JourneyMap tiles to regions used by Xaero's World Map - Watch the video guide

Description

• Reads images from the Journeymap folder
• Writes Xaero regions that are relevant for multiplayer maps (Singleplayer maps don't need this conversion, Xaero's mod will just automap everything over time)
• Confirmed to work with XaerosWorldMap_1.22.0_Forge_1.12.jar (MC version 1.12.2)
• Uses the Journeymap colormapping to decode what block likely generated each pixel
• Visual difference is significant, as Journeymap pixel colors are also affected by height level, shading, transparency, and biomes

Usage

Download the latest jar from releases (video guide)

java -jar JMtoXaero-3.0.jar <input folder> <output folder> <dimension> (the_nether, overworld, the_end, all)

Input folder should point to your journeymap singleplayer or multiplayer data folder, where overworld etc resides.

Example input: C:/appdata/.minecraft/journeymap/data/sp/2b2t_256k²_spawn_download/

Output folder should point to your XaeroWorldMap folder + server or singleplayer listing.

Example output: C:/appdata/.minecraft/XaeroWorldMap/Multiplayer_connect.2b2t.org/

Use the last argument to select a dimension or 'all' to process them all.

FAQ & Support

Newer releases of xaeros seem to have changed the world format and caused the Merger to no longer work, sorry.

• JMtoXaero generates 'old' xaero format, compatible with newer versions
• RegiontoXaero is designed for conversion of 1.12 terrain to 'old' xaero format, compatible with newer versions
• XaeroRegionMerger can only merge 'old' xaero formats (newly made JMtoXaero, newly made RegiontoXaero, pregenerated 256k files)
