This tool, a CLEO script lets you edit timecyc.dat (weather colors, properties) in game using a simple and intuitive UI.
Changes take effect immediately.
There are several other timecyc editors, but they they do not allow changes to be tested in real time and require the game to be restarted.
Or at least effects are not clearly visible until the game is maximized and timecyc.dat is reloaded again.
To select colors an HSV pallete with RGB & HSV spinners has been implemented.
Other spinners allow easy editing of other properties.
After editing the save button can be used to generate a new imecyc.dat file.
You're encouraged create your own timecyc.dat and share it up to GTA community.
What`s more - the project is released under open source license terms.
