World Geography Toggles: Bounded Sliders for Core World-Gen Parameters

OverviewTo give players more agency over their world layouts, this proposal adds a "World Geography" section to the main "Create New World" page. By exposing existing engine multipliers via safely bounded sliders (e.g., 0.5x to 3.0x), players can choose their macro-geography without an engine overhaul.Why It's Safe & SimpleNo Rehaul Needed: It uses multipliers on parameters the engine already calculates (like xz_scale, continentalness, erosion).Performance Protected: Bounded limits ensure block density and rendering loads stay stable, preventing crashes. Structures like villages will still spawn flawlessly.Full Parity: It works identically across Java and Bedrock devices.Proposed Sliders (Full details in the comments below!):Landmass Continuity: Toggle between localized island networks or massive continents with deep oceans.Biome Scale: Scales climate size so rare biomes (like Mangrove Swamps or Cherry Groves) generate as massive, immersive territories instead of tiny strips.Cave Frequency: Solves the underground "Swiss cheese" problem by letting players choose between isolated cave systems or dense labyrinths.Climate Weights: Balance or weight the map toward Cold, Temperate, or Warm zones.

    OverviewThe current procedural generation system produces stunning vistas, but it often leaves macro-geography at the mercy of extreme randomness. Players frequently encounter over-extended mountain ranges, microscopic or non-existent rare biomes (like Cherry Groves, Mangrove Swamps, and the Pale Garden) [1.19, 1.20], and highly fragmented landmasses.This proposal introduces a "World Geography" configuration section directly on the main "Create New World" page. By exposing existing noise function multipliers via safely bounded sliders, players can choose the style of their world canvas without any need for a procedural generation engine overhaul.
    The Core Technical Logic: Safe Boundaries & No Engine RehaulThis system does not require rewriting the underlying noise algorithms or 3D biome injection systems. It simply hooks into parameters the engine already calculates (e.g., xz_scale, continentalness, erosion, temperature, and humidity).To address performance and world-stability concerns, all sliders are strictly bounded between safe minimum and maximum limits (e.g., multipliers between 0.5x and 3.0x of the vanilla baseline).Performance Safety: Because chunk loading, block density per chunk, and max vertical limits remain unchanged, rendering loads remain perfectly stable.Structure Preservation: Safety bounds ensure that terrain slope gradients do not glitch, allowing villages, strongholds, and nether fortresses to continue spawning flawlessly.

    Bedrock & Java Parity: Because this applies basic mathematical multipliers to data-driven noise configs, a seed used with identical slider settings will generate identically across all devices—from high-end PCs to mobile platforms.
    Proposed Sliders & Their Structural Impact1. Landmass Continuity SliderWhat it alters: Scales the horizontal frequency of the Continentalness noise map.Low Setting: Creates a "Shattered Sea" profile—highly localized, vibrant island networks separated by oceans.High Setting: Creates a "Pangaea" profile—massive, sweeping continents with deep, expansive oceans to cross.
    2. Biome Scale & Consistency SliderWhat it alters: Scales the horizontal size parameters of climate zones.Low Setting: Fast-paced biome transitions every few hundred blocks, ideal for quick resource gathering.High Setting: Grand, realistic ecosystem boundaries. This guarantees that newer or rare biomes (like Mangrove Swamps, Cherry Groves, or future additions like the Pale Garden) generate as expansive, immersive territories rather than three-chunk-wide strips [1.19, 1.20].
    3. Cave System Frequency SliderWhat it alters: Governs the density/count of subterranean noise cuts within a fixed 6–12 chunk radius.Low Setting: Solves the underground "Swiss cheese" problem. Caves remain distinct, isolated networks. This preserves surface structural integrity for massive builds and revives strategic underground exploration.

    High Setting: Highly interconnected, continuous cavern labyrinths for players seeking intense underground survival.
    4. Climate Weight Selectors (The Biome Picker)What it alters: Adjusts the mathematical weights of the three native climate bands (Cold/Snowy, Temperate/Normal, Warm/Desert).Centered State: A perfectly balanced, logical progression from polar climates to equatorial zones.Asymmetrical States: Allows players to weight a world heavily toward a specific theme (e.g., a dominant "Ice Age" frozen continent or a sun-baked "Wasteland"), while keeping non-dominant biomes as legendary, ultra-rare discoveries.
    Why This Benefits Minecraft’s EcosystemThis does not make the game "easier"—it expands player agency and long-term world retention.Builders gain immediate control over their creative canvas directly from the front page, saving hours of aimless flight or third-party mapping.Explorers gain meaningful progression. Crossing a biome or charting long-distance infrastructure like high-altitude Nether networks becomes a grand, rewarding expedition because the geography matches the effort.Future-Proofing: Any new biome Mojang introduces automatically benefits from this system, naturally adapting to the scale and climate weights chosen by the player.
