Some Spring Drop 2025 sound events have incorrect attenuation distance and volume configurations

XMLWordPrintable

    • Unconfirmed
    • Multiple

      Some sound events from the Drop 1 2025 experiment have a different volume or max_distance than intended. These fields work together to provide the correct attenuation distance for a sound.

      A sound which has a max_distance greater than 16, but only plays at 1.0 volume, will not be heard from farther than 16 blocks away. The sound engine culls the sound because the volume is "too low" to be heard by the player, despite the max_distance setting.

      The volume of a sound must be set to at least 0.25 * max_distance whenever max_distance is greater than 16 to avoid sound engine culling.

      Affected Sounds:

      block.firefly_bush.ambient

      • This sound has a max_distance of 64, but a volume of 1.0. This means the sound will not play from greater than 16 blocks away.

      block.leaf_litter.place

      • This sound is only supposed to be audible from 16 blocks away, not 64, so the max_distance value needs to be changed to 16.

      block.leaf_litter.step

      • This sound is only supposed to be audible from 16 blocks away, not 64, so the max_distance value needs to be changed to 16.

      block.leaf_litter.break

      • This sound is missing the max_distance field used on the leaf litter place and step, causing it to fade much sooner than the other sounds. This sound should have a max_distance of 16.0.

      block.sand.ambient.attached

      • This sound is missing the "max_distance": 16.0 configuration used for all other ambient block sounds, even the sounds from 1.21.50. This means it will be far too quiet in-game.

      block.sand.ambient

      • This sound has a max_distance of 64, but a volume of 1.0. This means the sound will not play from greater than 16 blocks away.

      block.deadbush.ambient

      • This sound has a max_distance of 64, but a volume of 1.0. This means the sound will not play from greater than 16 blocks away.

      Correct Configurations

      Sound Event max_distance volume
      block.deadbush.ambient 64.0 4.0
      block.leaf_litter.break 16.0 1.0
      block.leaf_litter.place 16.0 1.0
      block.leaf_litter.step 16.0 1.0
      block.firefly_bush.ambient 64.0 4.0
      block.sand.ambient 64.0 4.0
      block.sand.ambient.attached 64.0 4.0

      Expected Result

      Drop 1 2025 sounds are configured correctly, so sounds with max_distance greater than 16 are audible from their full range.

      Observed Result

      Drop 1 2025 sounds are not configured correctly, so the sounds with a max_distance of 64 are actually only audible from 16 blocks away.
