Licenses/Media
Note
The following licenses are suitable for media files (images, models, sound files…):
- CC0 1.0 or newer;
- CC BY 4.0 or newer;
- CC BY-SA 4.0 or newer.
The default contribution license is CC BY-SA 4.0, unless you specify another license, by contributing to Unvanquished you are placing your work under CC BY-SA 4.0 license. You must have right to.
Older licenses like CC BY-SA 3.0, CC BY-SA 2.5, and CC BY-SA 3.0, CC BY-SA 2.5 are fairly acceptable for importing existing media. Many of our older media use such licenses, but please not use those older licenses for brand new content when you have full power to use latest version of those licenses. If you can get permission from original author to get a newer or more permissive license, please get it. For Creative Commons licenses older than 3.0, please ask us before merging.
