Introduction

Cloud Shadows FX is a lightweight, high-performance effect that renders dynamic cloud shadows and an optional top-down cloud layer over your scene. It works with Unity's Built-in and URP render pipelines (Unity 2022.3 LTS or later).

Key Features

• Real-time cloud shadows — projected onto terrain, buildings and objects using a screen-space approach
• Top-down cloud layer — optional visible cloud plane with configurable coverage, thickness and lighting
• Profile system — store all settings in reusable ScriptableObject profiles
• Coverage mask — paint or clear shadow areas at runtime via C# API
• Shader integration — sample cloud shadow attenuation from your own shaders
• Day/night awareness — shadow direction follows the directional light rotation
• Minimal overhead — single full-screen pass; no volumetric raymarching
