Greyfall adds a new biome, the Grey. It's rare (about as rare as a jungle) and everything in it has lost its colour. Trees, grass, flowers, stone, even the water. When you walk in, the screen slowly goes grey and the music stops. Only a low hum is left.
It lives in the dark parts of the Grey. It's a heap of ash with no face, it's slow, and it never leaves the biome. If it hits you, you'll feel heavy for a while. It doesn't like light. Hold a torch and it keeps its distance. Light up the place where it lives and it falls apart into grey ash.
NeoForge 1.21.1, GeckoLib and TerraBlender. Install it on both the client and the server.
I tested it with Sodium, Iris and Complementary shaders, and on a dedicated server.
In config/greyfall-common.toml you can turn the biome off or make it more or less common. Server operators also get /greyfall grey <radius> and /greyfall color <radius> to turn an area grey or bring its colour back.
Feel free to put it in your modpack, you don't need to ask.
Greyfall is a small piece of something bigger I've been working on. I can't say much about it yet. More is coming.
