Unity offers an Asset Server add-on product for easy integrated versioning of your projects. If you for some reason are not able use the Unity Asset Server, it is possible to store your project in any other version control system, such as Subversion, Perforce or Bazaar. This requires some initial manual setup of your project.
Before checking your project in, you have to tell Unity to modify the project structure slightly to make it compatible with storing assets in an external version control system. This is done by selecting Metafiles in the dropdown for Version Control. This will create a text file for every asset in the
Assets directory containing the necessary bookkeeping information required by Unity. The files will have a
.meta file extension with the first part being the full file name of the asset it is associated with. Moving and renaming assets within Unity should also update the relevant
.meta files. However, if you move or rename assets from an external tool, make sure to syncronize the relevant
.meta files as well.
When checking the project into a version control system, you should add the
Assets and the
ProjectSettings directories to the system. The
Library directory should be completely ignored - when using external version control, it's only a local cache of imported assets.
When creating new assets, make sure both the asset itself and the associated
.meta file is added to version control.
First, let's assume that we have a subversion repository at
svn://my.svn.server.com/ and want to create a project at
Then follow these steps to create the initial import in the system:
InitialUnityProject. You can add any initial assets here or add them later on.
Librarydirectory inside your project directory.
svn import -m"Initial project import" InitialUnityProject svn://my.svn.server.com/MyUnityProject
InitialUnityProjectdirectory if you wish.
svn co svn://my.svn.server.com/MyUnityProject
ProjectSettingsdirectory are versioned.
Librarydirectory in step 4 above.
svn propedit svn:ignore MyUnityProject/
svn ci -m"Finishing project import" MyUnityProject
