Blend Swap uses the Creative Commons license system. We've decided to use three licenses for all the models on Blend Swap. We've done this to keep licensing as simple as we can on the site while still offering authors a variety of ways to distribute and protect their art.
The following is a short enumeration of how every License applies:
This license lets creators and owners of copyright-protected content to waive all copyright interests in their works and thereby place them as completely as possible in the public domain, so that others may freely build upon, enhance and reuse the works for any purposes without restrictions under copyright.
You should be aware that by choosing this license you are granting the entire world (where applicable by law) to use your work for any purpose, even without the requirement to credit you. Be careful with this license because once you marked a blend as CC-Zero it's out of your hands, forever.
This license lets others distribute, remix, tweak, and build upon your work, even commercially, as long as they credit you for the original creation. This is the most accommodating of licenses offered, in terms of what others can do with your works licensed under Attribution.
This license grants everybody in the world (where applicable by law) permission to use a blend for any purpose, even commercial, but under an Attribution requirement, that is, the original author asks to be credited for the blend in the derivative works of the work users. If a user of the blend will not credit the original author the user has no permission to use the blend.
This license lets others remix, tweak, and build upon your work even for commercial reasons, as long as they credit you and license their new creations under the identical terms. This license is often compared to open source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use.
This license grants everybody in the world (where applicable by law) permission to use the blend for any purpose, even commercial, as long as they credit the original author of the blend and redistribute their derivative works under the same license. If you use a CC-BY-SA licensed blend, you MUST credit the original author of the blend and your derivative work MUST be released under the same CC-BY-SA license to the rest of the world.
Creative Commons enables Blend Swap to operate under the premise of providing free/libre blends to the world, and enables our community and features to keep growing under the rights granted to all of us by the authors who share their work on the site, enabling us to serve their works to the world and them to get exposure in the Blender community.
All blends hosted on Blend Swap are usable for any purpose, even commercial, as long as you respect the license the blend is under.
Blends under CC-0 (Creative Commons Zero) license can be used without ever asking for permission, for any purpose, even commercially. You are advised to give attribution but you are not required to do so.
Blends under CC-BY (CreativeCommons-Attribution) license can be used for any purpose, even commercially, but you have the obligation to credit the author. If you can't credit the author, for example, because you are using the blend in a TV spot, where credits don't exist, you MUST message the author of the blend to ask for a license exclusion, but it's up to the author of the blend to give this permission. Blend Swap will not intermediate in these transactions. If the author refuses to give the exemption permission you will not use the blend.
The rule above applies also for blends under CC-BY-SA (CreativeCommons-Attribution-ShareAlike) license and its extra SA clause. You can message the author asking for exclusion of either of the clauses or both, but it's up to them to give the permission.
When using the blend in a film production, include the author in your credits roll.
If in a rendered still image, include a text file with the downloadable image file, or add their credit to the image description meta data.
If you are uploading a new updated version of the blend to Blend Swap, please include a link to the original blend in your blend description in this format:
This blend uses <a href="http://www.blendswap.com/url/to/the/blend/"> Name of the Blend </a> by <a href="http://www.blendswap.com/author/profile/url/"> Author Name </a>, originally released under <a href="http://www.blendswap.com/licenses/"> *ORIGINALLICENSE* </a>
You are advised to keep the license the same as the original, but you can "upgrade" them in these two ways
CC-0 → CC-BY or CC-BY-SA
CC-BY → CC-BY-SA
No other license change is allowed.
