In this tutorial I will show you how use the snow add-on in Blender.
Activating the Snow Add-on
The snow add-on is a free add-on that comes with Blender
You will need to go to edit > preferences > add-ons and search for snow
Activate the add-on and save your preferences
Using the Snow Add-on
I will be using a simple scene I’ve already set up
Using the N-key, I can open my side panel and select the “real snow” tab
One thing you need to do is make sure your normals are facing the correct direction or you will run into problems
For example, If I turn on face orientation under the overlays menu, I can see that my ground is red which means the normals aren’t facing the correct way
I can fix this by going into edit mode and using ALT + N and choosing “recalculate outside”
If I select an object – my ground for example – I can simply click on “add snow”
Now my entire ground is covered in snow
However, I do have some control over the coverage
I will use CTRL + Z to undo the snow
Under the snow options, I can change the coverage amount
If I change it to 30-percent for example, only 30-percent of my ground is covered in snow
One advantage to using this add-on is that it will take geometry into account
For example, if I add snow to one of my rocks, notice how the snow will only show up on top of the rock – just like in real life
I also have the ability to change the height of the snow
For example, I can select another rock and change the height of the snow to 0.5 and have 6 inches of snow on top of the rock
If I only want snow in certain places, I can select an object – like my well – and in edit mode, choose the faces where I want the snow to accumulate
Then, without deselecting the faces, back in object mode I activate “selected faces” and add the snow
The snow will only accumulate on the faces that I selected
