Technical Details;

BT-2D Enhanced Flora Overhaul is a high-performance, fully customizable shader system designed to add realistic wind simulation and interactive foliage to your 2D game environments. Leveraging advanced GPU-driven calculations, this package provides optimized, dynamic, and physics-aware plant movement while maintaining seamless performance on all platforms, including PC and mobile.

Shader System & Features

Multi-Layer Wind Simulation

• Uses Perlin Noise & Sinusoidal Wave Functions for organic wind motion
• Supports variable wind strength and direction
• Smooth and natural oscillations with turbulence simulation

Real-Time Character Interaction

• Plants bend, sway, and react when characters pass through them
• Adjustable interaction radius and response intensity
• Automatic elastic return to original position

Advanced Motion Controls

• Flexibility Factor: Controls how easily plants sway in the wind (0-1)
• Turbulence Strength: Adds random variation to movement intensity
• Secondary Motion: Generates layered movement for extra realism
• Vertical Motion: Allows foliage to move slightly up and down, mimicking real-world dynamics

Dynamic Customization via Inspector

• Exposed Shader GUI settings for full artistic control
• Customizable wind patterns, intensity, noise variation, and plant reaction speed
• Per-material wind parameters to create diverse environments

Performance & Optimization

GPU-Optimized for High FPS

• Vertex animation-based wind motion reduces CPU overhead
• Utilizes Shader Graph & HLSL optimizations for maximum efficiency

Mobile & Low-End Hardware Support

• Toggleable Mobile Optimization Mode for reduced shader complexity
• Simplified Wind Mode for lightweight rendering on performance-limited devices
• Supports low-resolution noise maps to reduce GPU workload

LOD & Performance-Based Rendering

• Distance-based wind intensity scaling for improved optimization
• Smart culling system prevents unnecessary calculations for off-screen objects

Compatibility & Integration
