UPDATE - 4.15
Hi Guys , just updated the system with major performance optimization , so anyone who was experiencing a framerate lag can now get the dynamic daynight cycle in realtime.
My Advanced Day Night Cycle is finally released in the marketplace. So this thread will be a support and feature request thread.
Marketplace Item - https://www.unrealengine.com/marketplace/daynight-cycle
Short Description - This pack consists of a blueprint based daynight system with colour grading blend textures.
Long Description - This system takes into account the realistic Solar and lunar position based on latitude , longitude , time of day and day of year. It also contains several colour grading textures which blend over the period of 24 hours , from Dawn to Night. This system also calculates Lunar phases. A Clock system and a calender system are present to accurately calculate date and time.
Technical Details -
639 Lookup textures
2 materials and 1 material instance
2 main Blueprints and 3 widget blueprints
Kindly let me know if I need to send additional information.
The Blueprint performs the following main functionalities -
-Sets DateTime functionality, like Clock and Calender system based on given date and time.
-Calculates Sun’s elevation and azimuth angle and moon’s elevation and azimuth angle for a given date , time , latitude and longitude
-Calculates Moon’s age to accurately determine moon phases in a given date and location. Used a Spheremask for moon.
-Blends between different colour grading textures to choose the most accurate texture that fits a given time of day. For every transition between two different times of day (e.g dawn and early sunlight) , there are approx 40 colour grading textures blending within the time interval , so that the blend is smooth and not noticeable to the human eye. Along with the colour grading texture , the minimum and maximum brightness as well as the colour grading intensity in the post process element highly changes the look and feel of a given time of day, and that can be easily adjusted to get desired result.
Please note that in this pack the major focus was given to the blueprint functionalities rather than graphical quality, however if you want this pack to be enriched graphically as well , kindly request for any features here , and I will definitely try my best to add those features in the next release.
