Overview#
Immersive Weathering is a transformative Minecraft mod that introduces dynamic environmental changes to the world, making it feel alive and reactive. The mod focuses on 'environmental storytelling,' where blocks change over time based on their surroundings. Iron blocks rust in the rain, moss creeps over damp stones, and leaves accumulate under trees.
Every mechanic is designed to be non-destructive; weathering does not 'grief' builds but adds aesthetic character. Players have full control over these processes through various tools and items, allowing for the reversal or prevention of any weathering effect.
Core Mechanics#
The mod operates on several core systems that govern how blocks interact with the environment.
Weathering and Aging
Blocks undergo state changes based on 'Random Ticks' or specific environmental triggers like proximity to water, biome humidity, or heat sources.
Maintenance and Prevention
- Waxing: Similar to copper, most weathered blocks (like iron or mossy stone) can be waxed using Honeycomb to lock them in their current state.
- Scraping: Using an Axe on rusted iron or mossy blocks will revert them to a previous state or clean them entirely.
- Shearing: Shears can be used to specifically remove moss or foliage from blocks, often yielding the moss/foliage as an item.
Humidity and Temperature
Weathering effects are biome-dependent. Rusting occurs significantly faster in humid biomes (Jungles, Swamps) or during rain. Cracking occurs in hot biomes (Deserts, Badlands) or near heat sources like Lava.
Rusting System#
Iron-based blocks now feature a multi-stage oxidation process similar to vanilla copper. This affects Iron Blocks, Iron Doors, Iron Trapdoors, and Iron Bars.
| Stage | Description | Reversion Tool |
|---|---|---|
| Unaffected | Standard iron appearance. | N/A |
| Exposed | Slight orange tinting on edges. | Axe (Scrape) |
| Weathered | Significant rust coverage. | Axe (Scrape) |
| Oxidized | Fully rusted, deep orange/brown. | Axe (Scrape) |
Rusting Conditions:
- Rain: Exposure to rain accelerates rusting.
- Water Proximity: Being adjacent to water blocks or submerged triggers rusting.
- Biomes: Humid biomes increase the base rate of oxidation.
Vegetation and Growth#
The mod adds several layers of biological growth to the world.
Moss Growth
Moss will naturally spread to Stone, Cobblestone, Stone Bricks, and Deepslate variants if they are near water or in a humid environment. Players can manually apply Moss Clumps to blocks to instantly convert them to their mossy variants.
Leaf Piles
Leaves will occasionally drop Leaf Piles on the ground beneath them. These piles can accumulate up to several layers deep, similar to snow layers. They come in variants for every tree type (Oak, Spruce, Birch, Jungle, Acacia, Dark Oak, Mangrove, Cherry).
Weeds and Wild Grass
Grass blocks will slowly grow taller foliage over time if left undisturbed. This includes short grass, tall grass, and occasionally wildflowers, depending on the biome.
New Blocks#
Immersive Weathering introduces several new utility and decorative blocks found through world generation or weathering.
| Block | Source | Use |
|---|---|---|
| Silt | Found in riverbeds and lakes. | Can be crafted into Silt Bricks or used as a soil component. |
| Peat | Found in swamp biomes. | An efficient fuel source for furnaces. |
| Humus | Created by composting or found in forests. | High-nutrient soil that speeds up crop growth. |
| Icicles | Form on the ceiling in cold biomes. | Decorative; can fall and deal damage if the support block is broken. |
| Bark Blocks | Crafted from 4 Bark items. | A decorative block with the bark texture on all six sides. |
| Iron Bars (Rusted) | Weathering of Iron Bars. | Decorative variant of iron bars. |
| Cracked Mud Bricks | Formed when Mud Bricks are near heat. | Decorative variant. |
Items#
Bark
When a player uses an Axe to strip a log, it now drops Bark items corresponding to the wood type.
- Usage: Bark can be placed back onto a stripped log to restore it to its original state. It can also be used to craft Bark Blocks.
Moss Clump
Obtained by shearing mossy blocks.
- Usage: Can be thrown or used on blocks to spread moss. It is also a crafting ingredient for mossy block variants.
Tallow
Obtained from killing certain animals (pigs, cows).
- Usage: Acts as an alternative to Honeycomb for waxing blocks to prevent weathering.
World Generation#
The mod enhances the natural landscape with several new features:
- Icicle Caves: Found in frozen biomes, these caves feature large clusters of hanging icicles and frozen floor spikes.
- Silt Patches: Large deposits of Silt found at the bottom of rivers and oceans, replacing some sand or gravel.
- Peat Bogs: Found within Swamps and Mangrove Swamps, providing a source of Peat blocks.
- Root Systems: Tree roots now extend further into caves or hang from ceilings if a tree is directly above.
Recipes and Interactions#
Crafting Table Recipes
Bark Block:
- 4x [Any] Bark → 1x [Any] Bark Block
Silt Bricks:
- 4x Silt → 4x Silt Bricks
Humus:
- 1x Dirt + 1x Rotten Flesh/Bone Meal → 1x Humus (Note: Specific recipes may vary by configuration).
Interaction Recipes
| Action | Input | Result |
|---|---|---|
| Apply Bark | Bark Item + Stripped Log | Original Log |
| Clean Rust | Axe + Rusted Iron | Cleaned Iron |
| Remove Moss | Shears + Mossy Block | Clean Block + Moss Clump |
| Wax Block | Honeycomb/Tallow + Block | Waxed Version (Stops aging) |
Configuration#
Immersive Weathering is highly customizable via the immersive_weathering-common.toml file. Server administrators and players can adjust:
- Tick Rates: Adjust how frequently rust, moss, or leaf piles grow.
- Toggle Features: Disable specific mechanics like iron rusting or wood stripping dropping bark if they do not fit the playstyle.
- Block Blacklists: Prevent specific blocks from ever weathering.
- Growth Conditions: Modify the required humidity or temperature levels for various effects.
