TUNA Deferred shader

Platform: Minecraft Bedrock

visual system: Vibrant visual

Author: PRATUNA

Version: 1.6.0

🌟 Main Shader Features (TUNA Deferred Shader v1.0.1)

🌓 Deferred Lighting & Soft Shadows

• Next-Gen Lighting: The lighting system adds deeper immersion to every scene. Bright and dark areas transition naturally, making sunlight, moonlight, ambient light, and local light sources look truly three-dimensional.
• Soft Shadows: Shadows are significantly softer and more natural than standard Minecraft. Shadows cast by trees, mountains, buildings, and objects look smooth and realistic rather than harsh or artificially sharp.

🎨 Colors & Visual Atmosphere

• Dynamic Colored Lighting: Light sources emit their own distinct colors! Torches and lanterns cast a warm glow, Soul Torches emit blue light, Redstone shines red, lava glows orange, and Amethyst or portals radiate purple. This brings caves, builds, farms, and interiors to life.
• Cinematic Day & Night Cycle: Lighting and sky colors dynamically shift throughout the day. Experience warm, golden tones during sunrise and sunset, and deep, atmospheric hues at night.
• Vibrant Color Grading: Features enhanced color vibrancy and contrast powered by cinematic ACES tone mapping. Grass, leaves, water, and skies look much more vivid and eye-catching than Vanilla.
• Biome-Based Atmosphere: Every biome has its own unique mood. Deserts feel warm and arid, snowy tundras look cool and crisp, swamps appear dark and humid, while the Nether and End receive dramatic, otherworldly visual overhauls.

💨 Advanced Fog & Environments

• Volumetric Fog: Fog features real depth and height variation instead of being a flat screen color. It perfectly simulates distance across mountains, forests, caves, and faraway horizons, while also improving underwater and weather transitions.
• Enhanced Environments: Major visual improvements to the sun, moon, clouds, sky, and general world colors to deliver a truly cinematic presentation across the Overworld, Nether, and End.

🌊 Realistic Water Effects

• Improved Water & Normal Maps: Water includes animated waves and detailed surface movement. The integration of normal maps and heightmaps gives a deep, dynamic look to oceans, rivers, and lakes.
• Water Caustics: Animated light reflection patterns appear on underwater surfaces, realistically simulating sunlight passing through moving water.

🛠️ Advanced Material Technology (PBR Support)

• Full PBR Integration: Fully supports Minecraft Bedrock’s PBR (Physically Based Rendering) material system. This enhances how blocks display metalness, roughness, emissive brightness, and intricate surface details.
• Normal Maps & Heightmaps: Selected materials (especially water) utilize high-quality normal and heightmaps to create simulated depth and physical surface textures without altering actual block geometry.
• Emissive Materials: Key glowing elements and particles (like Glowstone, Sculk, and Vibration Signal particles) use dedicated emissive data to realistically pop out in dark environments.
• Partial PBR Coverage: Please note that PBR support is currently configured as a partial setup. Selected materials feature custom PBR data, while others utilize the engine's default material values.

⚠️ Technical Requirements & Compatibility

• Designed for Vibrant Visuals: This shader is specifically optimized for the modern Minecraft Bedrock graphics pipeline, fully utilizing Deferred Rendering and Vibrant Visuals-style workflows.
• Game Version Required: Minecraft Bedrock 1.21.90 or newer is highly recommended to fully support the modern lighting, atmospheric scattering, advanced fog, shadows, and color-grading features.
• Bedrock Edition Only: This is a dedicated Minecraft Bedrock resource pack (.mcpack). It is NOT compatible with Java Edition (OptiFine / Iris).
• Hardware Support Disclaimer: The shader cannot bypass hardware limitations. Your device, GPU, Minecraft version, and graphics settings must officially support Bedrock's Deferred Technical Preview / Preview features for the shader to function.

📱 Performance & Optimization Guide

• Medium-End Device Compatibility: This shader can be tested on mid-range devices. It works best when maintaining a moderate render distance and avoiding the simultaneous use of multiple heavy, high-resolution texture packs.
• Not a Lightweight Shader: Due to advanced rendering features—such as soft shadows, dynamic colored lighting, volumetric fog, atmospheric scattering, and water caustics—this is considered a medium-to-heavy visual pack, not a lightweight/low-end shader.
• Demanding Performance Scenarios: Players may experience FPS drops in heavy environments. This includes complex caves with dense light sources, large villages, highly decorated builds, massive Redstone rooms, underwater depths, the Nether, the End, thick fog, or high render distance setups.
• Recommended Settings for Best FPS:
  1. Start with low graphics settings in the Deferred menu.
  2. Use a moderate render distance.
  3. Avoid layering with other high-res resource packs.
  4. Test performance across different environments (Day, Night, Caves, Nether, and End) to find your device's sweet spot.
• Performance Disclaimer: A stable 30 or 60 FPS cannot be universally guaranteed for all mid-range hardware. Performance heavily depends on your device's specific GPU, RAM, screen resolution, world complexity, and other active resource packs.
