What is Fast Sky

Fast Sky is an extension of default procedural skybox shader, providing additional support for clouds and night elements (moon and stars). The skybox is rendered in real-time meaning that, the entire atmosphere is generated directly in the fragment shader allowing for infinite detail without impacting texture memory or build size.

Features

• Performance : One of Fast Sky's core strengths is its minimal performance impact. This ensures that adding stunning skies and clouds to your scene doesn't bog down your game's framerate, leaving valuable resources for other critical game elements.
• Real-Time Generation, Zero Pre-processing: Fast Sky dynamically generates cloud structures in real-time without needing to worry about any time-consuming pre-processing steps or bulky texture atlases. This drastically reduces both runtime GPU memory consumption and your game's overall build size.
• Intuitive Workflow and User Interface: Fast Sky Yasy-to-use workflow and UI, making the process of creating and customizing skies incredibly straightforward.
• Layered Clouds: Fast Sky allows you to stack up to four distinct cloud layers. This multi-layered approach enables the creation of mesmerizing cloudscapes.
• Animatable Cubemap Sky and Stars: Fast Sky allows you to dynamically integrate and animate traditional cubemap skyboxes and stars.
• Night Sky: Fast Sky features night skys elements such as moon and stars. It also support day-night transitions which is dependent on the direction of the sun. This effortlessly allows you to integrate day and night cycle's in your game.
• Versatile Visual Styles: Fast Sky is highly adaptable to both stylized and realistic visual styles. Its flexible design allows you to seamlessly integrate a wide range of artistic directions, ensuring your skybox complements your game's overall look and feel.
• Ready-to-Use Presets: Fast Sky comes with a selection of provided presets and demo scenes. These pre-made sky configurations serve as excellent starting points, which you can then easily expand upon to perfectly suit the unique needs and artistic direction of your game.

Limitations

• Non Volumetric: Fast Sky isn't a volumetric solution due to performance reasons. This means you might not get a 100% physically accurate lighting results, however the approximations made still tend to produce realistic and good-looking results.
• No Clouds Flythrough Support: Since Fast Sky is a non-volumetric background shader, flying through clouds is not possible.

In essence, Fast Sky empowers Unity developers to create dynamic, visually captivating skies with unprecedented ease and efficiency, all while maintaining optimal performance.
