使用git对unity3d项目进行版本控制

The following is an excerpt from my personal blog.

Using Git with 3D Games

Update Oct 2015: GitHub has since released a plugin for Git called Git LFS that directly deals with the below problem. You can now easily and efficiently version large binary files!

Git can work fine with 3D games out of the box. However the main caveat here is that versioning large (>5 MB) media files can be a problem over the long term as your commit history bloats. We have solved this potential issue in our projects by only versioning the binary asset when it is considered final. Our 3D artists use Dropbox to work on WIP assets, both for the reason above and because it'smuch faster and simpler (not many artists will actively want to use Git!).

Git Workflow

Your Git workflow is very much something you need to decide for yourself given your own experiences as a team and how you work together. However. I would strongly recommend the appropriately namedGit Flow methodology as described by the original author here.

I won't go into too much depth here on how the methodology works as the author describes it perfectly and in quite few words too so it's easy to get through. I have been using with my team for awhile now, and it's the best workflow we've tried so far.

Git GUI Client Application

This is really a personal preference here as there are quite a few options in terms of Git GUI or whether to use a GUI at all. But I would like to suggest the free SourceTree application as it plugs in perfectly with the Git Flow extension. Read the SourceTree tutorial here on implementing the Git Flow methodology in their application.
