Tried that but there is no TimeOfDay folder in the Crouch Valley route folders. Thanks for the sarcasm and rudeness by the way. 3) Copy the four .bin files in this folder named after each season and paste them into the TimeOfDay folder of your chosen route. If the naming convention differs for the relevant route, re-name accordingly so the new files match the naming of the old.
The files won't be in the Content\Routes folder. Check in the RailWorks\Assets for any folder named Developer\CrouchValleyAssets or similar. I don't have that route so I can't provide any more detailed instruction. If you don't find any TimeOfDay folder, look for a RouteTemplate folder.
You can copy the files into the Kuju ToD folder. BUT this will ofcourse change every route that use the Kuju weather. (Which to be honest will be a good thing) Back up your kuju folder first!
Find the Route Folder in Contents and open the RouteProperties.xml. Scroll down to skies and it will tell you what folders are used. An example from NWC BR Blue attached with the bit highlighted.
Find the route Properties XML. And you can even change there and had an entrie to at the bottom of it to the AP/Weather/EP it will work that way too if you knowledged how to twitck this file.
