Bring Volumetric Clouds & Weather in Your Unity World

Own Product

Easy Sky is a remarkably user-friendly plugin for volumetric clouds, weather effects, and sky rendering for Unity, letting you take full control of every celestial element in your scene. 
ASSIST Software developed Easy Sky as a Unity Asset Store plugin for game developers, simulation engineers, and digital architects seeking a AAA-grade sky and weather rendering solution for Unity's High Definition Render Pipeline.

Easy Sky for Unity HDRP

Easy Sky is a high-end weather and sky system built for Unity HDRP. It helps developers and creators design realistic skies, dynamic weather, volumetric clouds, and atmospheric environments for games, simulations, VR experiences, and architectural visualizations.

Easy Sky is structured around independent systems that work together without locking teams into a rigid setup. Developers can configure clouds, weather behavior, zones, and celestial elements separately, making it easier to adapt the asset to different scenes, art directions, and performance needs.

Weather Zones allow multiple atmospheric conditions to exist inside the same Unity environment. A scene can move from a misty mountain to a dry valley or a rainy coastline, with smooth transitions that help the world feel more natural and alive.

The Challenge of Real-Time
Sky Simulation in Unity

Unity developers often need realistic sky and weather behavior, but manually configured scenes and static presets can limit immersion, accuracy, and flexibility. For games, simulations, digital twins, and architectural visualizations, the sky influences atmosphere, storytelling, and the overall realism of the user experience. The challenge was to help Unity developers:

Reduce manual setup for environmental scenarios

Create more dynamic, data-driven Unity sky experiences

Sky Rendering & Atmospheric Storytelling 

Easy Sky was built to solve one of game development's most persistent challenges. ASSIST Software engineered a system where artists can craft cinematic weather and sky experiences from day one, with no HLSL knowledge required.

The plugin gives developers a palette of 15 ready-made weather profiles to jumpstart their work, while remaining fully extensible for custom weather systems. Opt for one pre-made profile or build your own, Easy Sky elevates your work either way.

Real-Time Weather Data Pipelines
for Unity Simulation

Easy Sky integrates with Real-Time Weather PRO to pull live meteorological data into the Unity editor, delivering atmospheric accuracy that mirrors the real world in any geographic location and at any time of day. 

Live data is automatically mapped to Easy Sky's cloud density, weather profile, fog intensity, wind direction, and celestial positioning systems. No manual scripting required.

Sky System Architecture & Design

Easy Sky is built around a modular architecture that gives developers control over every major sky and atmosphere layer inside Unity. Each system can be configured directly through Unity’s Inspector, making advanced sky setup accessible without requiring custom code for standard use cases.

Independent Systems, Unified Control

Clouds, weather, zones, and celestial elements can be adjusted separately while still working together as one complete sky system.

Round check fill icon
Localized Weather Zones

Create different weather conditions inside the same scene, with smooth transitions between biomes, regions, or gameplay areas.

Round check fill icon
Flexible Cloud Rendering

Use volumetric clouds for depth and realism, 2D clouds for lighter performance, or combine both in one environment.

Frequently Asked Questions

1. Can you integrate AI into an existing software product?

Absolutely. Our team can assess your current system and recommend how artificial intelligence features, such as automation, recommendation engines, or predictive analytics, can be integrated effectively. Whether it's enhancing user experience or streamlining operations, we ensure AI is added where it delivers real value without disrupting your core functionality.

2. What types of AI projects has ASSIST Software delivered?

We’ve developed AI solutions across industries, from natural language processing in customer support platforms to computer vision in manufacturing and agriculture. Our expertise spans recommendation systems, intelligent automation, predictive analytics, and custom machine learning models tailored to specific business needs.

3. What is ASSIST Software's development process?  

The Software Development Life Cycle (SDLC) we employ defines the stages for a software project. Our SDLC phases include planning, requirement gathering, product design, development, testing, deployment, and maintenance.

4. What software development methodology does ASSIST Software use?  

ASSIST Software primarily leverages Agile principles for flexibility and adaptability. This means we break down projects into smaller, manageable sprints, allowing continuous feedback and iteration throughout the development cycle. We also incorporate elements from other methodologies to increase efficiency as needed. For example, we use Scrum for project roles and collaboration, and Kanban boards to see workflow and manage tasks. As per the Waterfall approach, we emphasize precise planning and documentation during the initial stages.

5. I'm considering a custom application. Should I focus on a desktop, mobile or web app?  

We can offer software consultancy services to determine the type of software you need based on your specific requirements. Please explore what type of app development would suit your custom build product.   

  • A web application runs on a web browser and is accessible from any device with an internet connection. (e.g., online store, social media platform)   
  • Mobile app developers design applications mainly for smartphones and tablets, such as games and productivity tools. However, they can be extended to other devices, such as smartwatches.    
  • Desktop applications are installed directly on a computer (e.g., photo editing software, word processors).   
  • Enterprise software manages complex business functions within an organization (e.g., Customer Relationship Management (CRM), Enterprise Resource Planning (ERP)).

6. My software product is complex. Are you familiar with the Scaled Agile methodology?

We have been in the software engineering industry for 30 years. During this time, we have worked on bespoke software that needed creative thinking, innovation, and customized solutions. 

Scaled Agile refers to frameworks and practices that help large organizations adopt Agile methodologies. Traditional Agile is designed for small, self-organizing teams. Scaled Agile addresses the challenges of implementing Agile across multiple teams working on complex projects.  

SAFe provides a structured approach for aligning teams, coordinating work, and delivering value at scale. It focuses on collaboration, communication, and continuous delivery for optimal custom software development services.
