My brain is snowbound...

In a winter activity “READ ME” file, Scott Clawson commented,

“I put this activity together with snow in mind. If you want the same look that I planned this activity with, I use KOSMOS with the JBQuietSnow1 set for Winter-Snow.”

Can anyone explain what is Kosmos and JBQuietSnow1?
I looked up Kosmos in Google. All I got was it appears to be an artificial snow flocking. That can’t be it. (?)

It was a program that you could make different weather environments for MSTS. In OR you can use the keyboard commands to change weather to your liking.

Edit: Search Kosmos in the library, they's plenty there, including the program itself. Again it was for MSTS so you'd have to run OR using MSTS Environments, or just use the keyboard commands and adjust the weather to your liking. I did a Winter Snow activity and change the weather to clean and sunny, which changed the entire prospective of the Route and Activity. Run the Activities the way you want.
Activities made in OR I find can be programed for weather changes, whereas those made for MSTS just used a basic weather for the entire activity. With OR you can change it as you like. I ran an Activity on Marias Pass which called for "Snow" where I changed it with heavy snow in the mountains and progressively (manually ) changed it to sunny and clear as I got into the plans.
