Hyper Dynamic Weather & Sky System v4
Build a world where weather changes the atmosphere and the way players prepare. Hyper Dynamic Weather & Sky combines regional weather, local effects, temperature, Day Night Cycle and Time Manager in one connected environmental system.
Key Features
Weather across the world
- Global weather: provide fallback conditions outside configured regional biomes.
- Regional biomes: give different areas their own weather rules, priorities and transition widths.
- Weather transitions: configure transition probabilities, frequency and duration.
- Weather profiles: sunny, cloudy, partly cloudy, overcast, rain, light rain, thunderstorms, fog, wind, snow, blizzard, sandstorm and hailstorm.
- Visual and audio changes: blend weather intensity, lighting, fog, particles and sound as conditions change.
Temperature and local conditions
- Global temperature: combine season and time of day for the base conditions.
- Biome temperature: apply the active weather condition temperature offset.
- Local modifiers: use control areas for shelter, interior conditions, fire influence and other local effects.
- Player feedback: connect temperature changes to Attribute Manager states such as wet, hot or cold.
- Surface and lens effects: use material parameter collections for weather attributes, world surfaces and lens effects.
Time, sky and gameplay integration
- Day Night Cycle included: connect sun/moon positioning to the changing world.
- Time Manager included: configure time progression, seasons, time zones and time changes.
- Gameplay notifications: use weather and temperature events in farming, attributes or your own game logic.
- Multiplayer structure: biome managers handle server-side conditions while the owning player controller applies local weather presentation.
Practical setup
Place a global biome, add section biomes where regions need their own conditions and configure their transition rules. Add the weather manager to the PlayerController so players receive biome events. Use local control areas for places such as interiors or heat sources.
Different conditions within the same world
- A baseline for the whole map: global weather provides the fallback, while regional biome priorities and transition widths determine how local areas take over.
- Temperature with several causes: season and time establish the baseline, active weather adds its offset and local areas apply changes for places such as shelter or a heat source.
- One weather state, several responses: use the same weather and temperature notifications for visual presentation, character states, farming or your own gameplay rules.
- Local presentation in multiplayer: server-side biome conditions feed each owning player controller, allowing the player to receive the conditions and effects relevant to their location.
Try the demo, then use the setup guide to build the weather profile for your world.

Frequently asked questions
Why Hyper?
The strongest public modular Unreal Engine framework available at this scale
Most studios keep tools like this internal. Hyper makes a serious technical foundation available to solo developers, indies, and teams.
Built from 75,000+ hours of Unreal Engine work
System design, Blueprint architecture, multiplayer patterns, documentation, testing, integration, iteration, and real production problem-solving.
Systems designed to work together
Inventory, crafting, equipment, interaction, UI, combat, attributes, multiplayer, AI, quests, dialogue, maps, progression, survival systems, environment tools, performance helpers, and more can all live inside one larger ecosystem.
Working systems with source
Hyper gives you functional systems, a modular structure and documentation, with source you can extend for your own game.
Architecture you can extend
Hyper is built around scalable architecture: gameplay tags, structured data, child Blueprints, clean overrides, reusable components, and clear project boundaries.
Start fast, grow cleanly
Build on the included systems, replace visuals, adjust data, create child Blueprints and connect features without rebuilding the same foundation from scratch.
Want to learn more about the Hyper ecosystem, architecture philosophy, workflows, and developer behind it? Read more here and get started (https://gamesbyhyper.com/docs/getting-started/start-here/).
How do I add this to my project?
This module is provided as a full project because it includes Gameplay Tags, collision settings, config settings and other project-level dependencies.
Use our free Integration Tool (https://gamesbyhyper.com/product/integration-tool/) to prepare the integration. It combines compatible Hyper projects and handles migration and the required project settings. Use matching Unreal Engine versions and compatible Hyper releases.
Your own character, GameMode or custom systems may still need to be connected. The Integration Tool walkthrough (https://gamesbyhyper.com/docs/getting-started/use-the-automatic-integration-tool/) explains the setup and what to check in the generated project.
Do I need to use other Hyper systems with this?
No. You can use your own systems.
Hyper modules are designed around interfaces, abstract classes, shared contracts and dynamic dispatch, so features are not tied to one specific implementation.
If a module demonstrates integration with our Inventory, Equipment, Interaction, Movement, NPC or another Hyper system, you can:
Use the included Hyper implementation.
Replace it with your own system.
Use our implementation as a reference for your own integration.
The supplied integration shows how the module connects to the rest of a game. You can connect your own implementation through the same interface, abstract class or integration point.
For example, Attribute Manager may demonstrate Equipment modifying attributes. That does not mean you must purchase our Equipment System. You can follow the same integration pattern with your own equipment system.
The module includes working gameplay and its integration points. Build on the supplied setup or connect your own systems where you want different behavior.
See how to adapt a module (https://gamesbyhyper.com/docs/getting-started/customize-modules/) and how the shared data and abstract classes work (https://gamesbyhyper.com/docs/project-foundations/datamanagement/).
Where should I put my own changes?
Keep your own Blueprints, UI and data in your project's folder, for example Content/MyProject. Use child Blueprints or replacement components for your custom logic where possible.
That keeps your changes separate when you update Hyper. If you edit the original framework files directly, you will need to merge those edits when updating. The folder structure guide (https://gamesbyhyper.com/docs/project-foundations/folder-structure/) explains where everything belongs.
Do I need to buy Day Night Cycle and Time Manager separately?
No. Dynamic Weather & Sky includes both Day Night Cycle and Time Manager.
Can different regions have different weather and temperatures?
Yes. Regions can use different weather conditions. Global, biome and local temperature values can also feed into your character and gameplay systems.

Review from FabThis system is really cool. It combines visuals with actual gameplay, and for player immersion it’s a must-have for me. With a bit of time investment, you can also connect it with other tools like Ultra Dynamic Sky if you want to. Definitely recommended. What I especially appreciate about Hyper’s products is the long-term support behind them. When I first saw their ambitious roadmap, I was skeptical, as I’ve seen many developers make big promises only to abandon their assets or take years to deliver meaningful updates. I’m happy to say that Eric and the Hyper team have consistently delivered, kept their modules updated, and continued expanding the ecosystem. It’s not just this module I recommend, but also the team behind it, the growing ecosystem of compatible modules, and the community that has formed around it.

Review from FabThe fact all these modules work hand in hand is amzing as it means we can continue to grab more and more modules without having to massivly alter anything as everything is made to coiside with eachother

Review from FabVery impressive set of Hyper systems, both complete, coherent, and very well designed to quickly build a game. The weather system is particularly well done, especially thanks to its region-based management. This allows different weather conditions depending on world zones, making the environment much more alive and believable. The day/night cycle and weather variations greatly enhance immersion and provide strong overall world consistency. The community support is also a big plus: the Discord is active, responses are helpful, and the team seems reactive when issues occur, which is extremely valuable even for beginners. Overall, this is a very powerful ecosystem that allows you to quickly go from an idea to a playable prototype.

Review from FabEverything they do is streamlined, and they just keep improving! I’m buying them out, well at least the pro template paired with 23 modules. If your new or lazy, this is a great way to begin!

Review from FabI’m 100% beginner as of feb 2026 with no prior unreal experience and very little knowledge of coding learned from over a decade ago. This one pairs great with the environmental building kit. Initially I was kinda stuck but the discord is live and full of useful information. I almost felt all was lost when my moon and sun were bugging but the hyper team sorted my problem out quickly after giving me some time to troubleshoot. Literally turned a 0 – 1 and like magic my world lit up. Dropped 3 actors into the level applied a couple components, fixed my bug and I was off😎 Weather system really brings the world together.

Review from FabI have a LOT of Hyper’s kits.. and for a lot it is plug in play for the basics. I have MST PRO as the base framework, and just plug in those that are relevant for my game like Dialog, companion, advanced NPC, lockpicking, Skills, quests, traps, unlock (learn), world map, weathertime, Skinning, body decompose, Mesh to Actor swap, Admin console, with chat.. and so on. Simple to understand, and gets you started with most key parts of any game framework I highly recommend, not just for the quality of the kit.. but the excellent support on discord. The very detailed documentation.

Review from FabPretty impressive the range this covers across weather, day, night. It does it very well. I did reimplement large portions to my liking but it was well designed so this process was smooth. And the vanilla implementation is great for most folks
