How to combine project

hi guys. me and my friends are making levels in different pc. so i was wondering how can we combine our work into one project?
he is doing the blueprints and other stuff while my work to design levels.

Either use a version control software, or migrate the assets between the projects.

hey kvogler. i was thinking about using a version control software. but i was interested in migrating assets. so my question now is that. for example my friend is editing the main character like he change the camera. when i migrate it to my project does it replace my main character blue print also ?
