Vanillative

• Ambience that makes your world that much more alive, and QoL that just makes sense.
  • Versions 1 up to 1.2 includes Terralith and Nullscape, with no nether modficiations;
  • Version 1.3 is meant for forever worlds: it removes all Worldgen changes, and you can safely remove Vanillative from a 1.3 world and upgrade to vanilla.
• Is fully compatible with Vanilla; Vanilla clients can connect to Vanillative servers, and vice versa.
• Based on Additive, which means better-than-OptiFine features and performance.
• Features and Plasmo Voice for easy multiplayer and voice chats.
  • Note World Host is not yet available for 1.21.8.
• Contains no data-pack-y features.

TL;DR: it is not really about what Vanillative is doing, it's more about what it's not doing: interfering with your gameplay. Vanillative only includes QoL features to make it the easiest it can possibly be for you to run your own server with friends.

Special thanks to Devin for maintaining Additive, and to Lukebemish for helping me figure out the Modrinth API.
