Utility Nexus Admin

v0.0.0-beta.4 - Shader System

Added

• Shader System — Built-in shader loader compatible with Sodium 0.8.13+ on NeoForge 1.21.1
• ShaderPackManager — Loads .zip/.jar shaderpacks from the shaderpacks/ folder
• ShaderPipeline — Compiles GLSL shaders (vertex, fragment, geometry) via LWJGL/OpenGL
• ShaderSystem — Reload listener registration and active-pack persistence
• ShaderConfig — Configuration stored in utility_nexus_admin.toml (active pack name, auto-scan)
• Iris-style external config support — reads <shaderpack>.zip.txt alongside the shaderpack (JSON and key=value properties formats)
• Shaderpack metadata support via pack.mcmeta (description, version)
• New mod icon

Shaderpack Structure

shaderpack.zip/
├── pack.mcmeta          # Optional: description, version
└── shaders/
    ├── main.vert        # Vertex shader
    ├── main.frag        # Fragment shader
    └── ...              # Additional programs (terrain, entities, etc.)

Built-in Shader Uniforms

uniform mat4 ProjectionMatrix;
uniform mat4 ViewMatrix;
uniform vec3 CameraPos;
uniform vec3 SunPos;
uniform float Time;        // 0-1 day cycle
uniform vec4 FogColor;
uniform float FogStart;
uniform float FogEnd;
uniform int RenderStage;    // 0=sky, 1=terrain, 2=translucent, 3=entities...

Technical Changes

• ShaderPackManager — ZIP/JAR scanning, metadata parsing, external .zip.txt config loading
• ShaderPipeline — OpenGL shader compilation, program linking, uniform caching
• ShaderSystem — Client-side initialization, resource reload listener registration
• ShaderConfig — TOML-backed active-pack persistence

Note: Compatible with Sodium 0.8.13+ without the class conflicts that Iris triggers. Does not require Iris/Oculus.
