# Changelog ## [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 info` command to inspect current hull integrity, depth, crack counts, and whether your sub is hermetically sealed or breached. - **Spawning Command:** Added `/submarineliana spawnradius` to 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 `NullPointerException` and 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.json` and 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`) in `PermanentWaterCullingTest` that 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.
