Real-Time Cloud Shadows in Unity: Optimized Shader Graph Workflow for Mobile & VR

In this video, I walk through a detailed workflow for creating real-time cloud shadows on a Unity terrain, with performance optimizations specifically tailored for mobile and VR projects. I start by showing how to generate a custom render texture using Shader Graph. Next, I demonstrate how to create a seamless black and white cloud mask in Photoshop using the 'Filter / Render / Clouds' function, which produces a natural-looking texture for the effect. Finally, I explain how to set up the directional light's cookie with the custom render texture to bring the scene to life.
