If you get something good working, please fire it back and I'll update mine. 👍
As promised, this is the RainFX I came up with real quick last night. The track is so big that i'm sure I missed something and I didn't waste much time on creating stream_edges. Just around the front stretch pitboxes and grandstands. I might fine tune this later tonight after dinner. The problem I had with yours was the road surfaces didn't get wet or puddle up. With this one they do. Maybe someone can take this and fix it up right if I don't get to it sooner.

For anyone who cares, since I didn't hear any complaints or suggestions for improvement, i'm going to release my final(?) Deutschlandring and Fonteny edits soon. I reached out to Fat-Alfie to make sure it was ok to release something that changes his tracks and he kindly said it was fine with one caveat. I can't include my own custom track skins for the trees, which i'm fine with. I have to much respect for the work he did on these tracks to question what he would perfer. So the only included track skins will be his original look with edited trunks so they don't turn orange and yellow in the fall. He gave me copies of the textures without the bottom moss on the trunks which I am very grateful for. I may include a readme file that has links to my own personal tree texture skins or require people to PM me for the link if they want to try them out.
