A free mod for Witcher 3, by KEEPER.

This mod is a very advanced and cool particle-based weather mod for The Witcher 3: Wild Hunt. In this mod, you can experience a new and improved weather system. You can see and feel the particles floating in the air, falling down, and sticking to objects.

You can change the temperature, precipitation, wind speed, and humidity. The particles are very realistic, and they move based on your actions. You can also set up to three different weather events. The first is the standard weather, which is based on how the world looks and feels in real life. The second is a cinematic realism, which changes the weather and particle effects to make the world look more realistic and unique. The last is a snowfall.

The most important thing is that you can set the particle density and size. It’s very easy to set up and use. You can also control how often the particles occur and how often they are updated.
