I dont know how but since I did a journey chapter last night every scenario or service I do has rain non stop and I dont know how to stop it.
You can change weather for timetable services before the start. As for scenarios, they have preset weather. They should be, at least.
Journey & scenario weather is preset and cannot be changed. In service mode you can choose the weather as you wish.
For your own scenarios the weather can be changed by setting it from the timetable mode screen, then backing out, enter scenario designer and start your scenario with the new weather. It’s an unofficial workaround.
Thanks for the reply, I got it sorted after doing a timetable service and setting the weather. Was just strange that it was happening in custom scenarios.
