This is an attempt at creating a flip book effect with Unity.
This repository includes some submodules. Before opening the project with Unity, not only the repository itself but also these submodules have to be synced up.
If you're using Git from the command line, please run git submodule init and
git submodule update in the project directory to sync the submodules. Or you
can just use the --recursive option when initially cloning the repository.
