Angelica

• The little Angle [sic] that supports shaders while saving your fps from a certain death -boubou
• Is it obtuse, or accute? -Caedis
• It's a cute angle -mitchej123
• It's the angel that pulls you out of OptiFine's hell -Roadhog360

What's in it

• Shaders - Iris backport & enhancements
• Terrain - Celeritas 2.5.12 (NH) with threaded chunk building and translucency sorting
• Default GL 3.3 core profile with Java based fixed function pipeline emulation
• Optional Renderer selection - OpenGL, or SDL GPU for Vulkan/Metal/Direct3D 12
• Batching and instancing for entities, tile entities, items, particles and weather
• Dynamic lights
• HUD caching
• Custom fonts and text effects
• MCPatcher - connected textures, custom item textures, custom colors, random mobs, better skies
• Bundled NotFine, zoom, FPS reducer

Status

• OpenGL + Celeritas terrain - Default
• SDL GPU renderer - Experimental
• Shaders - Generally Available
  • Complementary + Euphoria Patches is the primary compatibility target
  • Sildurs, Seus, and any other shaders might work
• MCPatcher features - Alpha
• HUD caching - Semi-stable

SDL GPU renderer

Optional, OpenGL is the default

• Vulkan, Metal (macOS) and Direct3D 12 (Windows) through SDL3
• Needs LWJGL3ify 3.0.25+
• Falls back to OpenGL when no device can be created
• Vulkan on macOS via MoltenVK from the optional angelica-moltenvk jar

Core Profile

Targets GL 3.3+ core profile

• FFP emulation via generated GLSL shaders
• Display list emulation
• Software matrix stacks and state management through GLSM
• GL_QUADS -> GL_TRIANGLES conversion
• Automatic transformation of mod shaders that use compat-only GLSL builtins (gl_ModelViewMatrix, texture2D, etc.)

Required Dependencies

• UniMixins >= 0.1.23
• GTNHLib >= 0.11.19
• NOTE: Some mods are not required, but a specific version is required if present - see: Minimum versions below.

Minimum versions (if present)

• LWJGL3ify 1.5.3+ (3.0.25+ for the SDL GPU renderer)
• Hodgepodge 2.4.4+
• ArchaicFix 0.7.0+
• CodeChickenCore 1.2.0+ - Threading issues below that
• Amazing Trophies 1.2.2+

Known (temporary) Incompatibilities

• Forge Relocation - Currently non Thread Safe; safe if not in use
• ProjectRed Frames - Currently non Thread Safe; safe if not in use

Potential Incompatibilities

• EndlessIDs - Compat commits have been made, might work, might not - not fully tested

Known Incompatibilities

• FalseTweaks - Not currently planned (Looking for volunteers) [Might work if you effectively disable most of the mod]
• RPLE - Not currently planned (Looking for volunteers)
• LiteLoader - Install LiteloaderLoader

Permanent Incompatibilities

• OptiFine [Disabled, won't fix]
• FastCraft [Disabled, won't fix]
• BetterFPS [Disabled, won't fix]
• OptimizationsAndTweaks [Disabled, won't fix]
• Neodymium - Untested, but unlikely to be compatible. (Chunk Meshing is definitely incompatible, other features might work depending on config)
• SmoothFont - Equivalent functionality added
• ClientFixer - Use a resource pack like GTNH-FTI-Standard-Font

Building

• ./gradlew build, ./gradlew test
• Subprojects: glsm (state manager, FFP emulation, backends), lwjgl3-backend, sdl-gpu, tracy-client, moltenvk
