Hi,
I make tutorial videos for Unity3d On Youtube and was wondering if I am allowed to make money (monetize) my videos?
Do I need written permission? A special license?
Thanks
Joe
p.s
I’m not really sure if this is the right place to ask, sorry if it isn’t 
You do not need any permission
(Forum would be better place to ask)
I asked recently to the unity support team about showing Unity editor screen captures on my YouTube channel, they contacted legal department and this is the answer =)
“We are generally okay with people using screenshots and videos of the Unity editor in action. However, they should not use the Unity logo in any way that implies that Unity endorses their tutorial. Basically, they should not use the Unity logo without permission to do so from legal in each case.”
Hope that answers your question~
