[May 29, 2026] - Abyss Dimension, Physical Lianas & Big Optimizations
New Blocks & Features
- Abyss Dimension: Reintroduced the custom deep-ocean Abyss dimension with dedicated biome configs and custom worldgen.
- Physical Lianas & Seeds: Added creepvines (submarine lianas) and creepvine seeds that grow, flow with water currents, and simulate realistic physics inside sublevels.
- PDA & Sound Effects: Added a custom PDA menu overlay and registered new ambient/warning audio cues for Leviathans (roars and class detection warnings).
- New Diagnostics Command: Added the
/submarine infocommand to inspect current hull integrity, depth, crack counts, and whether your sub is hermetically sealed or breached. - Spawning Command: Added
/submarineliana spawnradiusto spawn creepvines inside a radius with custom density/probabilities. - Client RAM Boost: Allocated 20 GB of RAM for the game client config to handle large sublevel structures smoothly.
Performance & Optimizations
- Global LOD System: Added a new LOD Optimizer (
LianaLODOptimizer) that automatically pauses/freezes physics and ticking on distant creepvines to save CPU/FPS. - Spawning Queue: Spawning multiple lianas in a radius is now staggered (closest to the player first) and freezes other lianas during creation to prevent lag spikes.
Bug Fixes
- Liana Sublevel Lighting: Fixed an issue where lianas in Sable sublevels rendered pitch black. They now dynamically fetch and reflect the real-world block light values (torches, glowstones, shaders) around them.
- Precise Pressure Calculations: Completely reworked pressure depth logic to measure depth block-by-block relative to the actual water surface rather than checking the center of the sub globally.
- Sinking & Crash Handling: Added a limit to how many blocks can implode at once to prevent audio/particle lag spikes, and ensured oxygen/life-support blocks are immediately destroyed when a sub sinks.
- Stability Fixes: Resolved rare
NullPointerExceptionand chunk-loading issues in the leak/compartment scanner, and fixed a concurrency deadlock in the Sable snapshot queue.
[May 27, 2026] - Experimental Branch Updates & Enhancements
Configuration & User Interface
- In-Game Mod Configuration UI: Implemented a new custom split-pane configuration screen (
HullStrengthConfigScreen) to allow editing block-by-block depth limits and implosion chances directly in-game. - Config Persistence: Changes made in-game are automatically saved to
config/submarine_hull.jsonand applied at runtime.
Pressure Physics & Visual Glitches
- Refactored Stress Cues: Restructured pressure calculations to only play metal creaking stress sounds and spawn water dripping particles when a block actually sustains crack or implosion damage. Blocks set to 0% implosion chance are now completely silent and dry.
- Configurable Floater Limits: Updated the Floater block to respect customized depth limits set in the configuration instead of using a hardcoded threshold.
New Items & Create Integration
- Survival Friendly: All custom blocks and items (including Phycological Membranes, Pressurized Glasses, and Floater variants) now have proper survival recipes, making the mod fully survival-friendly.
- Phycological Membrane: Registered and added the Phycological Membrane item, which can only be crafted by pressing a Kelp block under a Create Mechanical Press.
- Iron & Copper Pressurized Glasses: Reworked the generic glass pressurizer block into distinct Iron and Copper variants with new recipes, models, and textures.
- Colored Floater Variants: Added crafting recipes for Floater blocks in all vanilla wool colors.
Abyss Biome & Custom World Generation
- Abyss Biome: Introduced a deep ocean Abyss biome ALPHA
- Biome Modifiers: Implemented world generation modifiers for amplified, large biomes, and default world types.
Renders, Compatibility & Performance
- Early Startup Config Access Fix: Resolved an initialization crash (
IllegalStateException: Cannot get config value before config is loaded) inPermanentWaterCullingTestthat occurred when early-ticking client mods (such as Xaero's Train Map) triggered ticks before NeoForge configurations loaded. - Sodium & Veil Shaders: Integrated critical rendering compatibility mixins for Sodium and Veil pipelines.
- Sable Network Synchronizations: Resolved package de-synchronization issues under active tracking states.
- General Asset Cleanup: Removed outdated model textures and unused assets to optimize mod footprint.
- Sable Dependency Upgrade: Upgraded Sable to version 1.2.2 for improved sub-level physics and performance stability.
