Title is pretty self-explanatory. I've tried the usual method of applying the Sky and Weather Pack (I'm using the original version; I didn't buy 2.0), including renaming each TimeOfDay file to what the original, included filenames are as packaged with the VNHRR route. I just get total black, nothing else, so I'd appreciate feedback on what I'm doing wrong and how I can get the pack to work on the VNHRR.
I just tried it on my Springfield Line route by copying the Time Of Day files across and renaming them to the same name that they are given for that route. A couple of the scenarios come out black. I tried 3 scenarios, and on one, it worked, but the other 2 one locked up the game and the other one, everything was just black. So it appears they don't work properly with this route. As in the manual, AP basically say you try this at your own risk. I hope you renamed the original time of day files so you can go back to them.
Springfield route have it's own weather patterns that are used in a lot of the scenarios. These are not compatible with AP weather. As the AP manual says: Please note that these new skies/lighting MUST be used in conjunction with the weather patterns included in this pack. These have an AP prefix. Using other weather patterns will almost definitely result in the skies malfunctioning and a restart of the simulator will be required to return them to normal. I suppose this can be fixed by changing weather in the scenario.
Another way to change the weather for a scenario on a route is to do it through the TSC editor. Page 30 of the Sky and Weather manual shows you how to do this.
