Introduction
Prefab Variants are useful when you want to edit some instances created from a prefab.
They make managing objects easier, so this article explains how to use them.
We’ll also cover helpful improvements introduced in Unity 2022.
What is a Prefab Variant?
A Prefab Variant is a new prefab derived from an original prefab, where you can modify some properties or components.
In other words, it’s a way to create a new prefab variation based on a base prefab.
How to Create a Prefab Variant
To create a Prefab Variant, select a prefab instance in the Hierarchy, then drag and drop it into the Project view — just like when creating a regular prefab.
You’ll see a prompt like the one below; select Prefab Variant to create it.
How to Unpack a Prefab Variant
Like regular prefabs, you can unpack a prefab variant by right-clicking the object in the Project view and selecting Prefab > Unpack Completely.
How to Edit a Prefab Variant
Just like editing a regular prefab, you can enter edit mode for a prefab variant by double-clicking it or by selecting Open from the instance’s Inspector.
This time, I edited the prefab variant and added a light blue object.
Of course, any edits made to the prefab variant will not affect the original prefab instance.
What Happens When You Modify the Original Prefab?
Let’s try editing the original prefab here.
When we apply a green material to the original prefab, the change is also reflected in the prefab variant.
As you can see, edits made to the original prefab are also reflected in its variants.
It’s also possible to create variants of variants.
While creating too many layers of variants can make management complicated, Unity 2022 has improved variant management significantly.
By clicking this button in the Inspector,
You can check the original prefab and variants of the currently selected prefab.
Conclusion
That was an introduction to Prefab Variants!
If you’re using prefabs but still find yourself editing each one individually, definitely give variants a try—they’ll make your workflow much easier.
