Version 1.8.1:
– New texture
– Added physics for particles (update Snowflake addon)

Features:
– Add new texture and significantly increase the number of raindrops.

more affected by truck position relative to rain inclination.
It makes a huge difference and vastly improves perception of weather! Just try it yourself!

– New car splash trails
– Detailed description of config parameters in
\def\vehicle\interior_glass_config.sii in case you want to play around with the settings yourself
