Just wild speculation at this point. We know AP have been doing something with some weather patterns, but what they plan, if anything, is unknown.
On Alan’s stream when he showed off the signals and had AP on a voice chat on stream they spoke about the new weather enhancement pack
I really would love the new weather pack to do something for quick drives. There has to be some way to get weather triggers etc into quick drive scenarios.
The weather enhancement pack can only work within TS' limits. It is technically the same as any other sky. A skydome model, cloud band textures, and weather patterns that define the cloud layers displayed and their movement due to wind. The way a QD is setup, you simply can't, other than starting a QD and then alter it in the editor - which makes it a Standard scenario. All you can do is to exchange the default QD weather blueprints "RailSimulatorCore\Weather\SL_..." and their fallback patterns for disabled DynamicClouds "RW_") - but QD will not create a weather extension that can be script controlled. The TemplateScenario blueprint does not have any Driver Trigger instructions that could hold a script trigger nor does it hold any weather information - as that is inserted by the QD setup menu routine. So the AP Weather EP is still nothing more than a piece of data. Achieving what you want would need something like RWE2 which can manipulate the TS code at runtime.
I run live weather in RWE2 when doing a Quickdrive, and it looks pretty realistic to me everytime I look at the window in the realworld and compare to what is on screen in TSC
Brilliant pieces of data indeed , but without code (RailWorks.exe) and .dlls the data would be useless. Was trying to point out that what Kim wants can't be achieved with pure data - it needs code, an .exe which modifies the QD setup routine at runtime.
