This one route addon haven't played for a while It is an extension of the Feather River Canyon. The route looks foggy/smokey. I have disabled RE Enhancer, AP Weather and Reshade and set the weather to 12:00 noon, Summer and clear. Any suggestions on where to start. My TSC settings are set to highest, Ambient Occlusion off, motion blur off.
This is RailSimulatorCore sky. Looks like you are using modified TimeOfDay files, not the original ones. I'll check and make a screenshot. This is how Summer, 12:00, 1. Clear looks with the original Feather River TimeOfDay files (don't like that white sky colour). It seems you are using Kuju\RailSimulatorCore\TimeOfDay\Core_Summer.bin for some reason. You must have messed with the templateRoute (which is not necessary for this route to use AP weather) This is how it looks using SilverLining "3D 1.Clear" Don't know what exactly you have changed, but I'd bet deleting the TimeOfDay and TemplateRoutes folder in Assets\DTG\FeatherRiver should restore the route and use the .ap contents again. Btw, FR comes with some nice custom 3D weather causing interesting fast moving cloud shadows, worth checking out:
Thank you for your insight to the issue. BTW this is an extension of Feather River Canyon that I was involved with a few years ago. This added Portola and the Williams loop to the route. I did remove the AP weather folder from the route file and used Reshade to get the effects.
