How to Add Music for Modded Biomes and the Nether or End

The mod uses a tag-based system, which means it can serve music to biomes added by other mods as well as the Nether and End, without you editing each biome individually.

Use the Nether and End folders

For dimension music, place .ogg files named nether1–nether10 in the nether folder and end1–end10 in the end folder of your resource pack namespace. These play while you are in those dimensions, layered on top of the existing soundtrack.

Target modded biomes via tags

Because playback is driven by biome tags rather than hardcoded biome IDs, modded biomes that carry the relevant tags will receive the matching music. If a modded biome does not play your track, check whether it is included in the tag the mod reads for that music category, and add it through a datapack tag if needed.

Test in the right dimension

Travel to the Nether or End and confirm your tracks play. Keep filenames within the numbered pattern and in .ogg format, and reload resources after changes so the new tracks register.
