Powerful Features

Volumetric Clouds
Drag-and-drop Volumetric Cloud setup.
Easily control computational cost and performance impacts (profiled to <2ms at average quality settings).
Flex your artistic muscle with cloud density, cloudiness, lighting intensity, sun color influence, sky color influence, cloud layer height and thickness, as well as base and detail noise scale and speed.
2D Clouds
Set the speed for the cloud textures to pan through the skybox.
Configure the base color and shaded color for the clouds to easily fit your color palette.
Decide how much the sun influences the lighting of the clouds.
Change how much the clouds are affected by the color of the skies.
Easily transition from cloudy to clear skies with controllable cloud thresholds.
Modify the cloud and cloud shading sharpness to customize the look of your clouds – super soft and fluffy, or really crisp and stylized.
Uses custom UVs to ensure you can have clouds directly overhead without any UV “pulling” at the top of the skybox.
Time of Day Configuration
Configure any number of named “Times of Day” like Night, Dawn, Day, and Dusk with customized sky colors.
Control the size and color of the sun to fit your game’s atmosphere.
Easily skip to specific times in the day.
Control how long it takes to transition between different times of day.
Set the overall day length with a controllable slider to determine how long one real-life second is in-game.
Built-in blue noise dithering to prevent banding on soft sky gradients.
Easy-to-use toggles and controls for both the Day/Night Manager and Skybox Material.
