Unity 3D | Using Volumetric Fog & Mist
Below is a Unity 3D environment we created using Volumetric fog & Mist asset and the Meadow Environment - Dynamic Nature package from the Unity 3D asset store. We also added some forest animals to the scene for a more dynamic feel. The goal was a to create a Virtual tour of this beautiful forest. We will talk about the processes we took to get the scene to look fantastic.

Volumetric fog is now a standard for triple A games. In this demo we used The Volumetric Fog & Mist Kit we found on the Unity asset store. We've been using the volumetric fog tool for a number of projects over the years because of its ease of use and quality in games. You can quickly make a beautiful scene in your Unity 3D project stand out even more.
To create our environment below we used the Meadow Environment - Dynamic Nature package from the Unity 3D asset store. See video below if you want to know how the asset looks and how we used it in our scene. It's great for Unity 3D terrain design.
We added a few animals we also found on the Unity 3D asset store. That asset is called the Animals Pack Deluxe and it comes with a variety of animals including animal animations. They are prefabs so all you have to do is drag and drop into your scene.
You can download these assets below from the Unity 3D Asset store below
Volumetric Fog & Mist will give depth to your scene and give it a sense of realism. In our project below we created two scenes. We created a day scene to demonstrate the atmospheric depth with volumetric fog. Then we created a morning scene to create that beautiful crisp morning forest to demo straight the morning sun rays
You can adjust the look of your fog buy changing a few parameters to create a more smooth foggy scene to a windy foggy after noon. The kit comes with a few presets that you can use to get a feel of what you want for your scene.
Volumetric fog also gives you the ability to create god rays in your scene as well as light scattering. We recommend pairing this up with some post processing to really give your scene that finished looked. Check out our demo below on using Unity 3D post processing for our forest scene.
The volumetric fog kit also comes with the ability to create fog of war. This is great for anyone creating a multiplayer game where you need to hide the player from view. The volumetric fog kit is highly optimized to work smoothly with your scene.
After installing the Volumetric Fog & Mist navigate to your MAIN CAMERA and go to ADD COMPONENT and look for the VOLUMETRIC FOG & MIST SCRIPT.
