Changelog
Improved the texture of rain drops
Improved particle behavior
Addon added for trucks, which increases 3 times the number of particles for SCS trucks

– Add new texture and significantly increase number of raindrops.
– Improve physical behaviour of particles, now their spawn will be more affected by truck position relatively to rain inclination.
It makes a huge difference and vastly improve perception of weather! Just try it yourself!
– Detailed description of config parameters in \def\vehicle\interior_glass_config.sii in case you want to play around with the settings yourself

Important! Mod is fully compatible with both ETS2 and any other weather/sound mods, just give it a priority and place on top of others.
Personally to use it with Improved SCS Rain mod for better sound experience.
