FalseTweaks

FalsePattern's flagship tweaking, patching, and optimization mod.

Nightly (most likely broken) builds available here

NOTICE

This mod completely replaces Triangulator and AnimFix. Make sure you delete these two mods before installing FalseTweaks.

List of major features:

Multithreaded chunk rendering (compatible with OptiFine and FastCraft)
Replaced minecraft's quad-based rendering with triangle-based rendering
Fixed ambient occlusion and smooth lighting (vanilla bugs MC-138211 and MC-43968)
Optimized beacon beam rendering
Voxel-based item rendering that replaces the ugly vanilla renderer
Fixed light leaking between blocks on chunk boundaries
Tile entity render order fixes
Optimized animated textures
3D rails
Faster texture stitching, with an algorithm based on Packing2D
Fixed block light leaks
Multithreaded mipmap generation (way faster resource pack switching)
Multilayer items (see below)
An improved version of the Shift+F3 profiler

And all of these tweaks can be individually toggled on/off in the config!

Using multilayer items

Multilayer items are defined using mcmeta files, and require the VOXELIZER module to be enabled for them to function properly.

Example mcmeta format for a 3-layer texture:

{ "voxelLayers": { "layers": [1.0, 1.0, 0.5] } }

The mcmeta should be attached to the base texture without any layering, and the layers should have the name of the base texture with _0, _1, _2, ... numeric suffixes for each layer.

Example file layout:

myItem.png myItem.png.mcmeta myItem_0.png myItem_1.png myItem_2.png

Fixing known problems

Issue Potential solution Game crashes on startup,
forge log says MixinTargetAlreadyLoadedException Under the 00_modules category in the config,
set B:STARTUP_OPTIMIZATIONS to false. Game crashes on startup,
loading screen was already present (or fixing issue 1 didn't help) Under the triangulator category in the config,
set B:RENDER_HOOK_COMPAT_MODE to true. Crash with OptiFine Under the 00_modules category in the config,
set B:MIPMAP_FIX to false. Crash with ShadersModCore Standalone shadersmod is unsupported, use optifine instead. Crash with "IllegalArgumentException: Comparison method violates its general contract!" Under the 00_modules category in the config,
