🌊 TCA Weather System - Complete Environment System

Version: 1.3.0 Godot Version: 4.6+ License: MIT

🆕 What's New in v1.3.0

✅ Volumetric Cloud System

• Full 3D volumetric clouds with self-shadowing
• Cloud motion synchronized with wind direction & speed
• Adjustable cloud density, shadow strength, and coverage
• Moon illumination on clouds for night scenes
• Cloud shadows that realistically block sunlight

✅ Enhanced Fog System

• Exponential height fog with weather blending
• Fog depth falloff control for atmospheric perspective
• Fog intensity automatically responds to rain
• Separate fog color for sunrise/sunset hours

✅ Day/Night Cycle Enhancement

• Automatic color temperature shift (warm sunset, cool night)
• Sunrise haze effect with light scattering
• Night sky brightness control
• Seamless transition between day phases

✅ Rain Visual Improvements

• Rain tint for sky & clouds (weather-driven color blending)
• Ground wetness shader with roughness & metallic response
• Wetness dries naturally over time after rain stops
• Rain intensity affects fog density and cloud darkness

✅ Particle System Optimization

• Rain & snow particles batch-optimized for performance
• Intensity-based particle count & lifetime adjustment
• Mobile-friendly particle culling

✅ Editor Integration

• Weather parameters exposed in editor panel
• Real-time preview of cloud, fog, and wetness settings
• Quick-switch weather presets

✅ What's New in v1.2.0 (Previous)

✅ Dynamic Terrain Wetness System

• Automatically applies wetness texture based on rain intensity
• Supports wetness drying over time after rain stops

✅ Vegetation Interaction System

• Grass & foliage bending from wind
• Rain impact effects on vegetation

✅ Improved Performance Controller

• Auto-quality adjusts wetness / vegetation effects
• Mobile-specific optimizations

✅ What's New in v1.1.0 (Previous)

✅ Performance Optimization System

• PerformanceController with auto-adjust based on FPS

✅ Wind & Cloud System

• Global wind with gust & turbulence

✅ Weather Transition & Forecast

• Smooth weather blending
• Probability-based forecast system

✅ Core Features (v1.0.0)

Cinematic Water Rendering System

• Gerstner Waves, Dynamic Normals, Multi-layer foam
• God Rays & Spectral Highlights

Sky & Atmosphere System

• Rayleigh + Mie atmospheric scattering
• 3-layer dynamic clouds

Environment Management

• 10+ weather presets, Season system, Day/night cycle

🚀 Quick Start (v1.3.0 New Features)

Volumetric Clouds gdscript var sky = $EnvironmentManager.sky_material sky.set_shader_parameter("cloud_density", 0.3) sky.set_shader_parameter("cloud_shadow", 0.5) sky.set_shader_parameter("wind_direction", 45.0)

Wetness Effect gdscript var wetness = $TerrainWetness wetness.wetness_strength = 0.8 wetness.dry_speed = 0.1

Fog Control gdscript var env = $WorldEnvironment.environment env.fog_height = 10.0 env.fog_density = 0.15 * rain_intensity
