My team is full but if you have any past work you’ve done no matter how silly it is maybe you should post it up so that you might attract some teammates. If you don’t have any work go program something small in blueprints or make some simple models so that you DO have some work.
Also, you don’t NEED a team. You should still participate.
I am not endorsed by them but I started using Digital Tutors to learn Maya. Might be good to try something like that for learning. Also, the free Unreal video tutorials go over a lot of blueprint fundamentals. From there you can use creativity to make whatever you want.
