Core hotfix: 1.0.27 Fix 4 — shared camera viewing
Adds scoped, read-only shared SecurityCraft camera access. Players can bind cameras to a camera monitor and select any of its up to 30 bound cameras. For a non-owner to view, the server verifies a monitor held in either hand is bound to that camera in the current dimension. Existing spectator, loaded-camera, disabled/shutdown and availability checks remain intact. Camera ownership, configuration, redstone-control authorization and other SecurityCraft protections are unchanged.
Fixes the supplied Marvel Legacy crash: its player-only ceiling-camera angle handler now skips non-player/null camera entities, including SecurityCraft camera entities. Normal player/spider camera behavior and other viewport listeners remain active. No third-party mod JAR is modified.
Install this update on both the viewing clients and the host/server for shared access. Offline checks cover the real mod call sites, all 30 bound-camera selections, wrong-dimension/unbound/no-data rejection, the reported invalid cast and existing FWA/startup guards. Multiplayer and full in-game camera switching remain unverified.
Retained Fix 3 — FWA and startup compatibility
Fix 3 corrects the NeoForge startup error introduced by the previous hotfix probes. Earlier Fix and Fix 2 files have been archived; use Fix 3 instead. Startup probes now read original class resources without requesting unsupported untransformed bytecode from ModLauncher. Both actual startup entry points are exercised by the offline regression checks.
Restores compatible FWA 1.3.4 animation occlusion on EntityCulling 1.12 while preventing the obsolete FWA field-type crash. Uses the native EntityCulling backend with immutable client-thread snapshots and client-thread visibility updates. No third-party mod JAR is modified.
Work is bounded to 512 animation boxes per snapshot and at most 10 stationary refresh requests per second. Oversized/non-finite boxes, stale results, camera movement, overflow and world changes keep animations visible. Worker snapshots hold weak animation references; pending results clear on logout. Old EntityCulling 1.11.3 retains its existing FWA integration. Unknown worker API shapes skip the new adapter instead of forcing an incompatible injection.
This is a core-only hotfix, not the 13-component aggregate described below. Offline native API/visibility/lifecycle checks pass; in-game FPS and full runtime compatibility remain unverified.
Performance and compatibility crash fixes made for Kaan's Minecraft 1.21.1 NeoForge roleplay pack.
Includes targeted loading, model and texture fixes, plus animation and rendering compatibility improvements. Results depend on your world, hardware and installed mods; this is not a universal FPS booster.
Version 1.0.29 — bundled open-source components
-All upstream runtime JARs, source code, licenses and Unix build files are retained. Both original and distributed source hashes and the omitted-file list are recorded in the bundle.
One JAR now includes the original, unmodified AllTheLeaks 1.1.16, BadOptimizations 2.4.1, Clumps 19.0.0.1, FastSuite 6.0.7, FerriteCore 7.0.3, ImmediatelyFast 1.6.15, Ksyxis 1.4.6, Lithium 0.15.4, ModernFix 5.27.27, Noisium 2.3.0, ScalableLux 0.1.0.1, ServerCore 1.5.19 and Placebo 9.9.4. Each keeps its own mod ID, authors and configuration. Noisium is the official 1.21–1.21.1 release, not an independently versioned backport.
Original authors: Uncandango, Thosea, Jaredlll08, Shadows_of_Fire/Brennan Ward, malte0811, RK_01/RaphiMC, VidTu, 2No2Name, JellySquid, embeddedt, Steveplays28, Spottedleaf, ishland, Wesley1808 and their contributors. Their MIT, LGPL and file-specific GPL licenses remain in force. Source archives, licenses, original nested-library credits and exact binary hashes are supplied inside META-INF/style-optimization/. These are independently loaded components, not code claimed as original Style work.
NeoForge JarJar skips an embedded mod when the same mod ID is already separately installed. Compatible external copies take precedence, including older copies; their dependency ranges must still be satisfied. Sodium, EntityCulling and ARR-only mods are not bundled. This is not a replacement for every performance mod. No launch-time downloader, forced GC or automatic removal of installed mods is used.
Offline build/regression checks and the actual JarJar selector passed for standalone and mixed-component selection. This does not verify in-game mixin application, FPS or leak-free operation; test your own profiles.
Version 1.0.27 — retained core fixes
Adds smooth directional normal-player flight, small-player PAL/MPM item-grip repairs, bounded weak shape reuse, large vanilla ingredient lookups, immutable identifier hash caching, owner-aware NPC cache cleanup and a one-time JVM-to-menu startup display. Overlapping standalone caches yield to supported external optimizers.
The internal mod ID and existing compatibility repairs remain unchanged. Version 1.0.29 adds the independent components listed above while retaining these core fixes.
Before installing
This mod also removes selected items and blocks used by the pack's cleanup settings. Removed content may disappear from existing worlds. Back up your world first. Use matching versions and content-removal settings on the server and clients.
Only Minecraft 1.21.1 and NeoForge are required. Other supported mods are optional; you do not need to install them all.
