What is Breathful? This is modpack I've been working on for a while, its main purpose is to enhance the game's atmosphere and ambiance, giving life to nature and the overall scene of the game.
Throughout your gameplay, you'll notice subtle atmopheric feautres like butterflies, flocks of birds, godrays, animated clouds, and more.
The textures of nature has also been entirely remade, trees will have bushier leaves, branches coming out of them, and apples growing on them; This expansion of details applies to every other biome and ecosystem on the game, all of this while being able to join public servers with no problems at all, since every feature here is strictly effective on the world around you, not the behaviours of your client.
My full 18 minutes video on the topic, watch it if you'd like to know what each mod here does:

A modpack with every ambient, atmospheric, and naturalist mod you'd need!
