Is it forbidden to keep scenes and other materials used during Unity development in the public domain?

Question

open source

In pursuit of the question "How to organize development with Unity3D?"
I am the owner of a free Unity3D license and would like to put my project on github in the public domain (scenes, code).
Isn't this prohibited by Unity3D owners?

Answer 1

No, why would you? If you write a book in Word, Microsoft will not forbid publishing it :) Only if you use the built-in assets there and they get on the github, you will need to indicate that such and such files belong to Unity3D and the license for them differs from the rest of the code.
