This mod connects TerraFirmaCraft and Ars by placing Ars plants/bushes as naturally generated patches in TFC biomes.
All important parameters are configurable per plant/per profile (one file per plant). Ideal for servers that want to define spawn locations and frequency themselves.

Features

Configurable worldgen per plant (profile)
Biome selection (IDs or tags)
Frequency (rarity_chance)
Number of patches per chunk (count_per_chunk)
Cluster size / tries per patch (tries_per_patch)
Horizontal/vertical spread (xz_spread, y_spread)

Profile-based configuration:

one TOML file per plant
Works alongside standard datapack JSONs, but reads config values from TOML at runtime (no duplicate datapacks required)
Server-focused: clear separation per plant, easy maintenance

Installation

Place the mod into the mods folder.
Start Minecraft/the server.

Configuration

Each plant is referenced by a profile name in the worldgen JSONs (e.g. "sourceberry").
On first launch, the mod automatically creates the matching profile file, e.g.:
config/tfc_ars_compat/sourceberry.toml
Edit the TOML to adjust behavior, for example:

tries_per_patch = 32 xz_spread = 6 count_per_chunk = 1 rarity_chance = 24 biomes = ["#minecraft:is_overworld"] # Tags or specific biomes possible

Biome examples

Specific biomes: "minecraft:plains", "tfc:plains"
Tags: "#minecraft:is_overworld", "#tfc:is_temperate_forest"
Mixed lists are possible: ["tfc:plains", "#minecraft:is_forest"]

Notes

Config changes affect newly generated chunks.
A restart is recommended to safely apply new worldgen parameters.
The mod only adjusts worldgen; balance, recipes, and mechanics come from the base mods.

FAQ

Does the mod read Forge config values at runtime?
Yes. It reads TOML profiles at worldgen time (per plant), so JSONs don’t have to be “hard-coded.”

Can I control biomes entirely via profiles?
Yes. Server admins can specify the desired IDs/tags directly in the profile TOML.

Do I need to edit multiple files per plant?
No. Only the profile TOML, which keeps management clean and simple even with many plants.
