Time, Calendars & Celestial Environments for Unity
Tunal brings configurable time and calendars, location-aware celestial simulation, and dynamic skies into one Unity tool. Shape believable daily cycles or invent new rhythms for fictional worlds, using reusable profiles and runtime controls.
Time shapes how a world feels — and how its systems behave. Set simulated or real-world time, define calendars, model the sun and moon across locations and seasons, and reflect those changes in skies and lighting.
Create familiar environments or fictional worlds with their own chronology. Reusable profiles, scene-based contexts, and runtime controls help you build environments with consistent rules, without forcing every project into the same cycle.

01 / Time & Calendars
Work with simulated or real-world time, configure calendar structures, and manage dates across gameplay systems. Persistence support lets you save and restore relevant world state. From a familiar calendar to an invented chronology, you control how the timeline is represented.
02 / Astronomy & Celestial Simulation
Model solar behavior using date and location, explore seasonal shifts in daylight, and represent polar day and polar night. Lunar progression and moon phases add another celestial rhythm: a configurable foundation for building gameplay and presentation around the sky.
03 / Dynamic Skies & Atmosphere
Configure skies, atmospheric color, clouds, stars, and lighting through presentation settings and profiles. Move between grounded and stylized looks, from a gentle sunrise to a long, star-filled night. Lite and High Quality shader options offer different visual approaches, with platform compatibility to be confirmed for release.
04 / Flexible Architecture & Developer Tools
ScriptableObject profiles and dedicated inspectors keep parameters approachable. Runtime APIs let your project control time and location. Multiple Tunal contexts can coexist in one scene, giving different environments or views independent settings rather than a single global clock.
Add a Tunal context to your Unity scene. Define calendar, astronomical, seasonal, and visual settings with profiles and inspectors.
Connect the relevant presentation controllers to your context. Add independent contexts for environments that need different rules.
Control time and location through runtime APIs. Use persistence components when relevant state should carry between sessions.
Ideas for what you could build with Tunal. Gameplay systems are your own integrations.
Connect your survival systems to daylight, season, and latitude.
Invent calendars and use time information for story events and schedules.
Build daily rhythms and seasonal palettes around environmental state.
Explore solar position, daylight variation, and lunar progression.
Give distinct environments independent clocks and celestial settings.
Tunal is being prepared for the Unity Asset Store. Explore its capabilities and discover the systems behind its configurable worlds.
