Dynamic Surroundings has been updated for Minecraft 1.21.1, for both Fabric and NeoForge. This release takes a dependency on Architectury, meaning that it must be installed for the mods to work. Architectury does not currently support Forge for MC 1.21.1. I plan on making a Forge release once that support is available.

If you are looking for a Fabric 1.20.x versions, please refer to the Dynamic Surroundings: Fabric Edition project.

Features

• Enhanced Sound processing - performs calculations in the background, adding a reverb effect to spacial sounds.
• Individual Sound Control - Set key bind and activate in-game. Use this feature to block, cull, and control the volume at which sounds play. And as a bonus, you can play the sound to hear it.
• Biome sounds - Atmospheric sounds that play based on biomes in the area. Seamless blending of sounds as the player moves throughout the world.
• Fog density changes driven by biome, time of day, and weather.
• Hot block effects such as flame jets over lava, and steam where water hits a hot block. Hot blocks are things Lava, Magma, campfires, and a cauldron containing lava.
• Waterfall sound and visual effect - will trigger when flowing water is detected nearby.
• Replace Minecraft's thunder sound with improved versions.
• Remap of block step sounds to "improved" versions.
• Various "DS" client side commands for dumping configuration information. (I currently use these while developing. I do plan to document at some point for general use.)
• Custom debug HUD that can be accessed by key bind. Moves the Dynamic Surroundings clutter out of the traditional F3 display.
• Compatibility with Serene Seasons - variations in seasons and temperatures can influence effects.
• Dynamic Surroundings is compatible when connecting to a Vanilla servers. Both Fabric and NeoForge loaders can do this.

For menu support in-game, install Cloth-Config. Both the Fabric and NeoForge versions can use this mod.
