Hi Everyone,

Was wondering if anyone else thinks the rain effects in scenarios don't quite look realistic, in that the rain spots on the windscreen look a little large and the falling rain looks like thick white lines coming down? You could be mistaken for thinking it was snow instead of rain. The faster you drive the more it looks like a hose being sprayed on the windscreen.

When looking at some scenarios on Youtube I noticed one scenario from Matt Peddleston showed pretty similar to what I tried to describe above.

I have my settings nearly all on max. Using the 64 bit offering of Train Sim

My PC settings are i7 3770 CPU @3.40GHz, 16 GB Ram, NVidea GTX 1060 3GB

Depends on which weather pattern is enabled I'd say....you get this in all scenarios or a select few?

I think this is the Silverlining weather that is wrong - if you go into the railworks/data/SilverLining and open up the Silverlining.override file ( I use notepad ++ available freeware from here : https://notepad-plus-plus.org/) and look for [rain-streak-width-multiplier = 1.0] and see what it is set to; mine was set at 5.0 which results in big splodgy and unrealistic. Set it to 1.0 and re-run the same scenario see if it works?

The first thing to determine is just what weather pattern is in use---pointless editing one if it ain't the right one!

Hi gptech,

It seems to appear in all the rainy scenarios I have tried, I will try a few more today just to compare routes etc.

@ rededge,

I had a look like you said and it is in fact as you thought it was, set at 5.0 (SilverLining weather). I used 'Wordpad' to view this.

Hello,

I checked a number of other routes and the rain effects were all the same.

Decided to try and edit the 'rain-streak-width-multiplyer' from 5 down to 1 as suggested and fired up the sim again and it has indeed made a big improvement! Those horrible white lines coming down are significally finer and looks more realistic now although I can't make my mind up as to whether the rain drops are a tadge too large still? All in all a big improvement to what i was seeing earlier.

Thanks for that little nugget of info, worked a treat.

I tested this out on a few more routes and only found so far that the London Ipswich route shows larger spots of rain on screen but the all important thing for me with this fix is that horrid outside falling rain effect is much smaller and therefor more realistic. Can now enjoy driving in the rain again.

Many thanks for this fix.

Have a good one.

Are we talking about just the cab windows while inside the cab or the lines in the sky when using an outside view camera?
Or both views?

The ‘wet windows’ effect is done by means of a special texture. Most creators use the smallest 512 texture sheet to cover the windows. Some use a larger 1024 texture and get smaller drops on the glass.

Not entirely true. The rain drop size is determined by how much space on the texture the window(s) take up.
