URP Supported
UniStorm now supports URP for versions of Unity 2019.4.9 and higher. HDRP support is currently in development.
AAA Volumetric Clouds
UniStorm 4.0 brings the addition of a completely redesigned cloud system capable of creating AAA procedural, self-shadowing, PBR, volumetric clouds at a great frame rate and only using just one draw call! UniStorm’s clouds use the latest shading and performance techniques such as Temporal Reprojection and LODs. UniStorm’s clouds feature 4 quality settings and a volumetric and 2D option all capable of being changed at runtime or within the UniStorm Editor. This makes it possible to support many devices and computers. Easy to use API makes adding in-game quality control simple and painless. An example to do this is also included.
Built-In Photon PUN 2 Network Support
UniStorm includes everything you need to get UniStorm working with PUN 2 that syncs UniStorm's weather, time, and date with multiple players. An example scene is included.
Atmospheric Fog
Atmospheric fog which takes into account the sun and moon's light direction and color which is applied to the scene, UniStorm clouds, and the skybox.
Cloud Shadows
Efficient real-time screen space cloud shadows that match the current cloud cover and cloud formations for added realism and visual quality.
4k Stars with Accurate Constellations
UniStorm's night skies include 4k stars with accurate constellations. Options are available within the editor to control the intensities of the constellations.
Procedural Auroras
UniStorm allow users to customize auroras per weather type to adjust the intensities, colors, conditions, and more!
Performance
UniStorm's volumetric clouds feature Temporal Reprojection and LODs with 4 quality settings (Low, Medium, High, and Ultra) each properly calculated to be far more efficient than the previous setting. This allows UniStorm to be able to run smoothly on nearly any computer. No max Camera Far Clipping Plane distance is required thanks to UniStorm's shaders so any distance can be used.
Built-in Lightweight Option
UniStorm has a built-in lightweight 2D cloud options perfect for low end mobile devices or computers. Users can select the Mobile option from within the editor that will automatically apply all optimal settings without overwriting custom settings such as colors.
Dynamic Modular Weather
Modular Weather allows users to create custom weather types. Sand storms, auroras, hail storms, thunderstorms, etc are all possible. There are no limits to how many weather types UniStorm can use, and best of all, they allow users to use their own custom particle effects, settings, and sounds for each weather type. UniStorm comes with 31 weather types! These include, Auroras, 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!
Cloud Profiles
UniStorm features customizable cloud profiles that each weather type can use. This allows you to customize the clouds' appearance to give tons of variety to every weather type. With UniStorm’s cloud profiles, users are sure to find the perfect cloud style to suit their project.
VR & Mobile Ready
UniStorm's all in one system also supports mobile and VR (Both Multi and Single Pass). There's even an easy to use option that will automatically apply all of the optimal settings for the targeted platform while keeping users' custom settings!
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 (Built-in Render Pipeline Only)
UniStorm's 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 Procedural Lightning system 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 their games.
Included Examples
UniStorm includes 6 example scenes all demonstrating different functionality you can do with UniStorm. A save example system is also included that allows users to save their in-game time, date, weather, temperature, and more with both a manual and auto-save option. This data can then be loaded so users can pick up right where they left off.
The Editor
UniStorm’s editor's design has been heavy influenced by the feedback from its many users to be intuitive, powerful, and offer a low learning curve. UniStorm’s editor is 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. Tutorial videos and external documentation are included to help users get the most out of UniStorm.
CTS Weather Manager Support
UniStorm includes an external system to transition CTS's weather shader for when it rains or snows allowing your terrain to be shaded with snow accumulation and wetness. (CTS not included)
Additional assets shown are not included. The clouds cannot be flown through.
