Try this version from Legion, what I fixed partly a long time ago. Config from GitHub should be rather old. Don´t know if I ever updated it. Will take a look later and maybe update config with rainfx etc.

Edit: Ah, found an updated config. Imo
@KevinK2 made rain_fx, at least it looks like his work. I included it into my config after getting that part. Just tested it and no "glass looking sand", but nicer grass...
Edit 2: Oh, sorry. Rain FX part was from
@DiscoveryJoke. I credited him in config file (line 239).
