Okey, i know a lot of question ask about this topic. But i can’t find anything useful. We want work together at the same time and same project. I know its possible with a multi-user plugin. But in this plugin you must have lan connection. we are not in a same room and hamachi dosent work. Another question is when one of us’s computer is off and the other is working on the project. Can the project change even when the computer is off or must be open at the same time?
I would appreciate it if you could help me with these 2 issues.
I think you are mixing concepts here. That plugin you are talking about is about playing locally or in lan with the same game, nothing related to the game itseld. You should activate source control, UE4 works well with GIT. Just syncronize both computers, yours and your friends, to a git repository, and you will be able to work with the same code base.
You need to setup source control to be able to do this:
- Github
- Subvesion
- Perforce
You can use one of these, here is a tutorial for the github setup
As long as you are working on a local directory and not a networked one you will not have any issues, if you have never used git before let me try to explain. When one person has made a change to an asset and wants to share it you save, and push it to the others who then update their files to see the changes.
This being said you will need to ensure you are not working on a file currently being used by another person an example being if you are all working on the same level changes made to that level will require you re reload the level, things like new blueprints will automatically be added to the content browser once pulled.
Please mark this as answered unless you need more clarification
I download git but i understand you’re uploading your own project to the server. Your friend download that and he have the changes . The problem is, does he always have to download files that big? Also i download Perforce. It’s the same logic, but I think they work from the cloud system. The problem is that I could not connect my friend to my server. How can i do that?
Entire project gets downloaded once after that only the changes get downloaded nothing else changes are not normally big unless u are putting in model.
I have never set up perforce before but you would have to add him to your organization and he just pulls the repo same logic
Epic added multi user to 4.23 which will do exactly what you need just need to ensure everyone has the same project so i would recommend source control for that but afterwards it is easy here’s the tutorial Multi-User Editing | Live from HQ | Inside Unreal - YouTube
We are not in the same home. Multi user wants us to be in the same place but i am not sure. I will watch the tutorial. Did you use multi user before?
Thank you so much. I will look into it 
If you use a VPN you do not need to in the same location, if you dont have a vpn just stick to using source control
VPN didnt work. I dont understand how i can do that
