Time of Day Control within the Editor

UniStorm HDRP brings the addition of fully controllable time of day right within the Unity Editor. You no longer have to be in run-time to see your changes.

HDRP Volumetric Clouds

Physically-based real-time clouds with adjustable shape, density, and lighting. Fully integrated with HDRP’s sky and sun. Clouds can also be flown through when enabled.

HDRP Volumetric Fog

Light-scattering fog that adds depth and atmosphere. Supports height, density, and full interaction with scene lighting and shadows.

HDRP Cloud Shadows

Provides shading and cloud shadows based on the current cloud coverage.

HDRP Screen Space Global Illumination

Simulates indirect lighting and surface light bounce to produce more realistic lighting.

Stars with Accurate Constellations

UniStorm's night skies include stars with 25 accurate constellations.

Modular Weather

Modular Weather allows users to create custom weather types (through Scriptable Objects) with customizable settings for Particle Effects, Sounds, Volumetric Fog, Volumetric Lighting, Cloud Level, Cloud Height, Wind Speeds as well as overrides for Cloud Color, Fog Color, Sunlight Color, Moonlight Color, Reflection Lighting, Lightning Color, and Lightning Bolt Color. UniStorm will seamlessly transition between weather types and their settings each time the weather is changed or generated.

Included Weather Types

UniStorm comes with 34 weather types. These include, Blowing Leaves, Blowing Snow, Blowing Grass, Lightning Bugs, Clear, Mostly Clear, Partly Cloudy, Mostly Cloudy, Cloudy, Overcast, Foggy, Drizzle, Light Rain, Rain, Heavy Rain, Hail, Thunderstorm, Light Snow, Snow, Heavy Snow, Thunder Snow, Fire Rain, Firestorm, Dust Storm, and more!

Advanced Weather Generation

UniStorm generates weather based on the precipitation odds set from within the UniStorm Editor. The easy to use line graph allows users to set the odds for precipitation weather types for each month and UniStorm will generate weather accordingly. Summer can have less precipitation than Winter and vise versa. UniStorm has options to generate daily weather with a randomly generated start hour and hourly weather that's generated every in-game hour all based off the precipitation odds. If users don't want generated weather, there's an option to have static weather too.

Global Weather Shaders & Shading

UniStorm's HDRP Global Weather Shader allows objects to receive rain and snow shading during rainy and snowy weather types. Rain shading allows surfaces to get shinier, but only on surfaces no greater than 90 degrees. The inside of most surfaces will appear dry, such as inside buildings and roofs. Snow, will function the same, but with accumulative snow shading. The snow texture, snow bump texture, and snow specular level can all be customized. When the weather is not raining or snowing, UniStorm will fade out the weather shading.

Weather and Weather Transitions

UniStorm allows users to create an endless amount of weather types that UniStorm will use. Each time the weather is changed, UniStorm will seamlessly transition it according to the global transition speed. Each weather type can be customized with its own cloud cover, cloud style, cloud height, particle effects, sun intensity, moon intensity, cloud shadow intensity, sound effects, wind amount, and various other settings allowing for truly unique and customizable weather.

Procedural Lightning & Lightning Strikes

UniStorm’s Fractal Lightning system generates procedural lightning with branches. It also allows objects to be struck by lightning. Users can define the odds lightning has to strike the ground and objects. When a lightning strike happens, users are able to customize what effect is created. A fire effect can even happen with the appropriate tag.

Day/Night Cycle & Colors Control

UniStorm allows you to adjust all colors of the environment and sky for each time of day such as the sun and moon colors, ambient light colors, shadow and cloud shadow intensities, fog colors, sky colors, environment reflection intensities, and more! Each color also has its own individual color options for precipitation weather types.

Time, Date, & Built-in Calendar

UniStorm has a built-in time and date system that can help keep track of a player's in-game time. UniStorm's calendar is accurate and even the current time and date can be used.

Customizable Moon Phase System

UniStorm's customizable moon phase system allows users to build their own moon phases. There are no caps to the amount of moon phases UniStorm can use. Users can preview their moon phases, and set the starting moon phase, right from within the UniStorm editor. UniStorm automatically assigns all needed textures and updates the moon phase daily. Each moon phase also has their own moonlight intensity. This allows the new moon and crescent moon phases to give off less light than that of a full moon, if desired.

Weather Type Conditions

Optional Weather Type Conditions make weather types have to reach certain conditions for them to be generated from UniStorm's weather generator. These include conditions such as particular seasons and temperatures as well as the ability to only have certain weather types be called from custom events or programmatically.

UniStorm Profiles

Import and export your UniStorm settings to and from a UniStorm Profile. This allows users save their settings and transfer them between other UniStorm systems without having to manually apply colors and settings.

Time of Day Sounds and Music

UniStorm allows users to customize the sound effects and/or music that will play for each time of day. The amount of delay in between each sound effect and song can be customized. There's no limits to the amount that can be used.

Sound Manager

UniStorm's Sound Manager handles all of your UniStorm created sounds using a generated Unity Audio Mixer. This gives you precise control over the Master, Ambience, Weather, and Music volumes which can be usable with user built UI or can be controlled within the UniStorm Editor.

Built-in Events

UniStorm's built-in events can get called every in-game hour, day, month, year, and even during a weather change allowing users to easily create added functionality for games.

Included Examples

UniStorm includes 10 example scenes all demonstrating different functionality you can do with UniStorm.

UniStorm HDRP Wiki

The new UniStorm HDRP Wiki Site has improved tutorials and documentation.

The Editor

UniStorm has been greatly improved and streamlined for HDRP. UniStorm’s editor is also self-documented so every component is explained right from within the editor via Tool Tips.

API & Documentation

UniStorm's API can help with additional game mechanics and features such as accessing the temperature, time, date, current weather, forecasted weather, season, and more.
