CityWorld ReForged

Biome mods now reach every corner of a CityWorld world — and biomes look like themselves.

Three Minecraft versions: grab the jar matching yours and drop it in mods/.

⚠ Worldgen changes only affect newly generated chunks. Existing chunks never regenerate, so start a fresh world (or walk into unexplored land) to see the new biomes, ground and farms.

Added

• Biome mods work in CityWorld worlds. Biomes O' Plenty and most other modern biome mods register their biomes through TerraBlender, which CityWorld's own biome source never saw — so a CityWorld world with BoP installed got its 450 blocks and none of its 69 biomes. It now reads what those mods registered and folds them into the world. Measured with BoP installed: 113 biomes offered, 86 of them actually appearing. On by default — installing a biome mod is the intent; turning them off is the deliberate act (world.useModdedBiomes, or the Customize screen when such a mod is present). Costs nothing when you have no biome mods.

• Modded biomes get ground they can win. Two separate problems were measured, and both are fixed. Continentalness was scaled against extremes CityWorld's terrain never reaches, so it only ever emitted -0.78..0.54 where every other axis spans -1..1; it now measures its own ends and uses the full range. That alone was not enough — most unreachable biomes overlapped our ranges on every axis and still lost, because the climate lookup picks the nearest point and TerraBlender's regions field vanilla's biomes as competitors. So world.moddedBiomeShare (default 0.35, on the Customize screen) reserves a share of the map where the lookup runs with vanilla's points removed. Measured with BoP: 34 → 52 distinct modded biomes, 12.4% → 36.1% of ground, with CityWorld still naming about two thirds. 0.0 restores the previous behaviour exactly.

• The last few biome-mod biomes get a route to the ground. With Biomes O' Plenty installed, 54 of its 59 biomes already generated. Of the rest, spider_nest was fine (it is a cave-pool biome), and four never appeared for two different reasons. bog, fungal_jungle and snowblossom_grove lose the climate lookup everywhere — against vanilla, and against other modded biomes even at moddedBiomeShare = 1.0 — so there is no gap to widen and no share that reaches them; #cityworld:surface_pool now hands a listed biome a share of cells outright. gravel_beach was never asked about: shores are decided from terrain, and the modded lookup is deliberately limited to land above the waterline, so #cityworld:shore_pool stands a variant in on ground already ruled a shore. Patches respect the temperature and humidity the biome declared for itself, so a bog will not turn up in a desert. Both tags are datapack-driven, so the next biome mod needs no code.

• Biomes look like themselves. CityWorld lays its own surface and never runs a biome's surface rules, so a biome whose identity is its ground generated as ordinary grass or sand — BoP's gravel beaches were sand, its volcanoes grass. Ground is now data-driven two ways: biome tags (#cityworld:ground/gravel, /sand, /podzol, /coarse_dirt, /terracotta, /basalt, /mud, /stone) for vanilla materials, and a cityworld:ground data map for anything else — which is what lets BoP's lush_desert get its own orange sand, wasteland its dried salt and origin_valley its own grass, rather than a vanilla stand-in. Mappings came from BoP's own surface rules, not guesswork. A pack can add or override any of it.

• Three vanilla biomes were wrong too, in every world, mods or not: old_growth_pine_taiga and old_growth_spruce_taiga now get their podzol floor, mangrove_swamp its mud, and grove its snow dusting — a grove is a snowy forest at ordinary height, so it fell between the biome list and the elevation-based snow cap and got neither.

• Biomes O' Plenty's cave biomes join the cave pool — glowing grotto, crystalline chasm and spider nest turn up underground alongside the vanilla four. Shipped inert, so it does nothing unless BoP is installed. (Fungal jungle was in this list and has been taken out: it is a surface biome — its features are placed on the heightmap — so underground it generated bare stone.)

• Bigger biome regions by default. world.biomeScale now defaults to 1.5 rather than 1.0 — regions you can walk across rather than change three times on the way to the shops. The Customize labels moved with it, so "Default" names the step the setting actually starts on.

• Worlds are warmer, and ice caps mean something. Across a dozen worlds the world read cold — snowy biomes and iced peaks everywhere, and little desert. Two causes: the temperature field sat neutral, and the MODERN ice cap was purely a matter of height, so every mountain iced over even standing in a desert. The ice line now rises with temperature, so caps belong to cold places rather than to all high places; and world.climateWarmth (default 0.25, on the Customize screen too) leans the whole field warm — about 17% — without narrowing its range, so frozen peaks and deserts both still happen.

• Farm fields are a tag, so mods can grow in them. Crops come from #cityworld:farm/crops and flowers from #cityworld:farm/flowers (with #cityworld:farm/tall_flowers for the tall fields), each drawn per field so a field still reads as a field of something. Ships Farmer's Delight and Biomes O' Plenty entries marked optional, so they cost nothing until those mods are installed. Two-block crops work: BoP's barley is a half=lower/half=upper plant rather than an aged crop, so the planter checks for that and places both halves — which means any modded tall crop works, not just barley. Every vanilla flower is in the pool now, tall ones included.

• Farms look like farms. The crop mix was an even split, which put tilled fields — the thing a farm is for — at 11.5% of farm lots, behind trees, flowers, ground crops, pasture and grass, while fallow and ferns held ground that reads as empty from the air. The MODERN pools are now weighted: tilled 27.3%, pasture 22.7%, ground crops 14.1%, trees 12.7%, flowers 10.2%, grass 8.4%, fallow 4.7% — measured over 3,074 farm lots, not eyeballed. Each climate keeps its character: potatoes and beets in the cold, cane and melons in the jungle, cactus in the desert.

• Every bare container has themed loot, with a modder seam. Hospital, nightstand, shop, pond and the three vault rooms each get their own table, and each has an empty _extra companion table that a datapack can fill without touching CityWorld's own — so a gun mod can drop ammo into nightstands and rifles into the vault armoury.

• Permission nodes for every command. CityWorld gated purely on operator level, so a permissions manager could not grant or deny any of it — and op is all-or-nothing: handing a moderator /cityfind also handed them /cityschem, which writes blocks, and /cityexport, which writes files. Five nodes now split them up: cityworld.info (default everyone), cityworld.teleport, cityworld.find, cityworld.schematic and cityworld.export (default operators). Works with LuckPerms, SableCraft Standards' /rank, or nothing at all — with no permissions manager installed the behaviour is exactly as before, since each node's default is the old op check. The console keeps working regardless. See NODES.md.

• You choose who decorates the wild. On MODERN/APOCALYPSE, wild land was getting vanilla's biome features and CityWorld's cover, with no way to change it — which is why wild forests read lush. world.wildDecoration (and a "Wild plants" picker on the Customize screen) now takes BOTH (the default, unchanged), CITYWORLD for CityWorld's cover alone, or VANILLA to hand the wild over entirely — which is the interesting one if you have a biome mod installed, since it lets that mod's own plants and trees stand on their own.

• 26.2's cinnabar and sulfur build with the rest. Both new stone families join the MODERN and APOCALYPSE decorative palette, so cities on Minecraft 26.2 grow deep-red cinnabar and yellow sulfur buildings alongside the blackstone and copper ones. They are warm colours in a palette that was short of them. Stone buildings do not become any more common — the palette just has more stones in it. On earlier Minecraft versions the entries are simply absent.

• Palettes document how to take a block out, not just how to add one. NeoForge tags support a remove list, so a datapack can drop a single block — the sulfur, say — without replacing the whole palette. See PALETTES.md.

Fixed

• /cwlocate finds every biome the world has. It searched CityWorld's own biome matrix rather than the biome source, so biome-mod biomes, the surface/shore pools and cave biomes were invisible to it — vanilla's /locate biome could find them and CityWorld's could not. It now asks the same lookup the world generates from (and unlike vanilla's, it teleports).

• Wild plants are vanilla's on MODERN and APOCALYPSE. Running CityWorld's cover and vanilla's biome features doubled the planting and read as unnaturally lush. Vanilla's pass is also the half a biome mod extends, so on the modern styles it is the one worth keeping. Still switchable to BOTH or CITYWORLD per world.

• The F3 readout fits on screen. The level line was running past the edge; it is two lines now.
