Hi. I think it would be nice for Unreal Engine 4 to permit real-time collaborative development.
Basically, one person shares the level, others connect and can edit the level in real time. The person that shares it is responsible for the level (saving and so on). This could be extended at game level.
Here is a good article about the Pros and Cons of collaborative editing: http://www.altdev.co/2011/06/20/real-time-collaboration-for-games-development/ Collaborative development could work on level designing, but also on code/blueprint editing. Here is an example of collaborative code editing:
I think that having collaborative features inside Unreal Engine 4 Editor will speed up the people workflows a lot. What do you think? Could this be implemented ?
