Sourcing models
If you are not a modeler, suitable characters are easy to find in the Unity Asset Store and other commercial sites. It is possible to find rigged models without having to pay a lot of money, but if you are planning on using them in a commercial project, always check the licensing—typically a small word or text file is included in the zipped folder when you download a model.
The models used in this book are provided by Atelier Sphynx, more are available in the Unity Asset Store at https://www.assetstore.unity3d.com.
