Hi all,
I have a small tip for you for the Three Country Corner Route, sorry if this (or something similar) has already been posted here before.
In short: it consists in using the default kuju sky in 3CCR. Although it may look as a step backwards with those beautiful skies from TTB that 3CCR has, to me the route generally looks better, I get MUCH better viewing distance providing some great views in the Arlberg Pass never seen before (at least not by me) while keeping the blue haze; it also gives you mountain shadow effect, which I've never seen with the 3CCR default skies. It also removes the ugly brown hills/mountains when you set your sky to clear in QD.
Here's how to do it:
Go to the RailWorks folder then Assets\JustTrains\Austriaobjects\ and backup the whole TimeofDay folder somewhere (in case you would like to go back easily). then go to Assets\Kuju\RailSimulator\TimeofDay and use the files there to overwrite the files under Assets\JustTrains\Austriaobjects\TimeofDay renaming the EN name to the DE one in the process so that the filenames are kept the same for 3CCR:
Winter - Winter
Fruehling - Spring
Summer - Sommer
Autumn - Herbst
And you're done.
I think it is mainly a matter of personal preference, so some may not like this. I know that I myself will switch to those typical 3CCR skies from time to time - and there's nothing easier - just copy those original files back from the backup.
If you try this - please let me know what you think about the change. I haven't had enough time to test it thoroughly so there may be some issues I haven't noticed.
