I'm looking for a way to use the contens of the valve SDK online together with other people, but I cant find one?
Is there no way to host a hammer server for example?
So two or more people can work on a map at the same time.
If not, how do game dev's do stuff together?
Please help!

I need to know if there is a way to work on maps with multiple people at the same time , if not , how do game developers do it?
