These are just some clarifications about my interpretation of (and not a substitute for) the license. You should carefully review all of the terms and conditions of the actual license before using the licensed material.

1 - Using the CC-BY 4.0 license for models generated with ManuelbastioniLAB
1.5 - I used ManuelbastioniLAB to generate a 3d human, assuming CC-BY 4.0 option, then I modelled by myself 3d clothes and 3d hair. The texture were also painted by me. Can I release the resulting character with my own license, for example including restrictions to copy and redistribute it?
1.7 - My character contains some parts generated using ManuelbastioniLAB. According to the license, they are used under CC-BY 4.0, but the rest of the character (hair, clothes, textures) is created by me. I want to sell the resulting model: What is the best way to handle this case in my character license?

4 - Using the AGPL license for models generated with ManuelbastioniLAB
0.1 Can I use 2D renderings of the models created with ManuelbastioniLAB for commercial 2D comics, 2D videos, 2D illustrations?
Yes. Rendered two-dimensional images or two-dimensional videos of a scene that includes 3D models generated with ManuelbastioniLAB are not considered a derived product of the licensed 3D database and 3D base models.
Due to many factors (i.e. the transformation from 3D space to 2D space, the position and the type of camera used, the other 3D elements included in the scene, the position and type of lights, the post production, the composition of multiple characters, the path of the camera, ecc.) the original 3D data is fundamentally modified and transformed sufficiently that it constitutes an original work.
For this reason, the author of the 2D rendering is the sole copyright owner of 2D image/video created by him and the sole responsible for the use of his 2D image/video.
0.2 When downloading it I did not get a zip file but a folder with a lot of files and trying to install it in Blender does nothing. Can you help me?
Some browsers, for example Safari, have an option to decompress zip files automatically on download. You should change this in your preferences.
0.3 How can I help you in the development of the lab?
The best way to help the lab project is to increase its popularity. A project with a big community grows better and faster.
If you have a video channel (for example on Youtube), you can create your videos to review the lab or to explain how to use it, you can spread the word about new releases or new features, using your social pages or your preferred online places, you can also help newbie users replying to their questions. If you are a reporter you can also write articles about the lab and contact Manuel Bastioni to receive more info and news.
When you create your animations, graphic novels, comics, it would be nice to mention the use of the lab and contact the lab developer, so your work will be eligible to appear on the official social pages of the lab.
If you are a researcher and you have used the lab for academic publications or thesis, please contact the lab author: he likes to know the cool things done with the lab and show them to the other users.
Another way to help the project is providing high quality feedbacks and bugs report.
On the contrary, 3d assets (models, texture, animations, ecc.) created by external contributors are not used in the lab, because they involve bureaucracy and legal issues: identity of contributor, proof of authorship, transfer of copyrights, license agreement, etc. All 3d assets included in the lab are created from scratch by Manuel Bastioni.
0.4 Why the lab is not included directly in Blender official release?
There are three problems in inclusion of the lab in Blender:
- Characters matter requires a more complex license than the standard Blender output. The current lab license take account of a lot of things, for example, please take a look to the FAQ 1.8 here, that explains the importance of the "no-restriction" clause
- The lab is expensive in terms of package size. With the completion of texture editor, it will require more textures and perhaps it will gradually reach 100 MB
- The lab is released more frequently than Blender, and an integrated version can be quickly obsolete, creating confusion.
1.1 Can I sell models created with ManuelbastioniLAB if I choose the CC-BY 4.0 option?
1.2 Can I include models created with ManuelbastioniLAB in my closed source game, if I choose the CC-BY 4.0 option?
1.3 What should I do to respect the CC-BY for models generated with ManuelbastioniLAB?
Example of scenario: John creates three characters using ManuelbastioniLAB then John adds some alien clothes, hair and morphings modelled by him and puts them in his own closed source game, released with his "John's license"[*]
John must put in a visible place, for example in game credits or in game license a statement like this one:
"The 3d models A, B and C are generated using the open source tool “ManuelbastioniLAB” so A, B and C are derivative of the characters created by Manuel Bastioni (www.manuelbastioni.com) and are licensed under CC-BY 4.0. The alien morph, alien clothes and alien hair are created by John and released under John's license."
This is a good attribution, because Title, Author, Source, Changes and License are all noted.
*Remember that the adapter license ("John's license" in this example) cannot restrict the freedom of CC-BY parts, because it must respect the CC-BY "No additional restrictions" terms: You may not apply legal terms or technological measures that legally restrict others from doing anything the license permits. (In particular see the section 2(5) and 3(a)(4) of the CC-BY 4.0). Also the CC requires the description of the custom changes and the parts added by you, as in the example above.
1.4 Can I add license restrictions to models created with ManuelbastioniLAB, if I choose the CC-BY 4.0 option?
No. When you receive material under a Creative Commons license, you may not place additional terms and conditions on the reuse of the work. This includes using effective technological measures (ETMs) that would restrict a licensee’s ability to exercise the licensed rights.
1.5 I used ManuelbastioniLAB to generate a 3d human, assuming CC-BY 4.0 option, then I modelled by myself 3d clothes and 3d hair. The texture were also painted by me. Can I release the resulting character with my own license, for example including restrictions to copy and redistribute it?
See FAQ 1.3 above. In particular the note in the blue rectagle.
1.6 My game contains some models generated using ManuelbastioniLAB, while code, assets and music are created by me. How to handle this in the license of my game?
See FAQ 1.3 above.
1.7My character contains some parts generated using ManuelbastioniLAB. According to the license, they are used under CC-BY 4.0, but the rest of the character (hair, clothes, textures) is created by me. I want to sell the resulting model: What is the best way to handle this case in my character license?
See FAQ 1.3 above.
1.8 Why have you used the CC-BY? It has the "No additional restrictions" that limits my freedom. Why not the CC0?
This clause is required in any serious license to preserve the freedom of the users.
What will happen without it, for example, if 10 users generate the same character (using the same preset for the characters library, for example)
and one of them puts the effective technological measures on it? Should the other 9 ask his permission to use their character?
No, because the CC-BY fixes this problem with its "No additional restrictions" clause: nobody can add additional restrictions to the models generated with the lab.
Any user can include a CC-BYed character in his commercial or non commercial product (respecting the attribution, of course), protect his product with his license, but his license can't restrict the freedom of other users that want to use the same model.
A clause similar to this one is present practically in any commercial license, because, for example, if someone buys a model from a 3D store, he can't prevent others from buy the same model and use it for their purpose, and of course he can't complain that now the 3D store is selling his model!
Note that a similar restriction is implicitly applied to things released in Public Domain.
You can't get something released under Public Domain (for example with CC0) and put your copyright directly on it, because this will prevent others from using it.
Basically you can't say "this CC0 model now is mine and from now on nobody else can use it", because you are using a model that is... under Public Domain!
In other words, you can use a CC0ed model in your commercial package but you can't limit the freedom of others that want to use the same CC0ed model: anyone has the right to use something released under Public Domain.
So, under this point of view, the principal difference between a CC0ed model and a CC-BYed model is only that the latter requires the attribution. You can use a CC-BYed model in your commercial package that use your own commercial license, but your license can't prevent others from being free to create a similar model using directly the lab. For these reasons I choosed the CC-BY license.
1.9 Can I create a closed source character editor using lab characters?
The morphing database is released under the Open Source license AGPL (See the license page) in order to avoid that someone creates a closed source clone of the lab. Any attempt of reverse engineering to extract the morph library with the intention to release it with a different license is an AGPL infringement.
Anyway it was decided to consent a double license for the models generated by the official ManuelbastioniLAB software, so you can generate a character (that includes expressions shapekeys) and use it in your closed source game under the terms of CC-BY 4.0 (See FAQ 1.3 above.)
Thanks to the CC-BY option, you can also generate multiple CC-BYed characters and mix them in your closed character editor, but clearly you cannot use this as trick to extract a large portion of the morphing library, since it would be considered as reverse engineering.
Concerning the meaning of "large portion of the morphing library" see the FAQ 1.11
1.10 What happens if I modify the script to generate characters that include the lab morphs as shapekeys? Will I obtain a CC-BY morph library?
No. According to the legal terms, the double license can be applied only to the output of unmodified script. Any ouput from unofficial versions is AGPL only. In other words, your modified script is a bit reverse-engineeringish and will break the double license option: all the generated characters will be not CC-BY, but AGPL. For details please read the section "LICENSE OF MODELS GENERATED BY THE SOFTWARE" in the license page.
1.11 How many lab characters can I mix in a closed source character editor?
The FAQ 1.9 says: "Thanks to the CC-BY option, you can also generate multiple CC-BYed characters and mix them in your closed character editor, but clearly you cannot use this as trick to extract a large portion of the morphing library, since it would be considered as reverse engineering."
Many artists asked for a better definition of "large portion" of database, since they want to include a CLOSED SOURCE character editor in their game using models generated with the lab with the CC-BY license option, but they have some doubts about the AGPL restrictions. Here are some guidelines to help them.
These notes are just a clarification: they ARE NOT PART OF THE LICENSE.
First of all, it's needed to quickly define some terms:
- "Character creator": The external software, part of a game, that works mixing a set of characters created with ManuelbastioniLAB.
- "Character class": one of the base categories available in ManuelbastioniLAB. To clarify with an example, in version 1.5 there are 15 available classes: Caucasian female, Asian female, Afro female, Caucasian male, Asian male, Afro male, Anime female style shojo01, Anime female style shojo02, Anime female style realistic, Anime man style shojo01, Anime man style shojo02, Anime man style realistic, Elf female, Elf male, Dwarf male.
- "User": The one who is using the lab to generate the characters and/or wants to create the character creator.
- "Morphs": Modelling morphs (also called "shapekeys") derived from the ManuelbastioniLAB database.
It's not easy to define a precise numeric threshold for extracted data, since it depends not only by the amount of morphs extracted, but also by their complexity and by their usage in the character creator. So the best way to help you is to give a practical example of a right usage that is NOT considered reverse engineering:
With the lab, for each character class, the user creates five types of bodies and five types of faces, then mixes them in its character creator. The character creator doesn't extract sub-features, like types of noses or types of eyes, but only interpolates whole faces and whole bodies. For example the character creator can create a new face with a linear interpolation like 0.3*face1 + 0.3*face2 + 0.4*face3.
The usage described in this example is OK: it permits to have a flexible character editor with hundreds of combinations, but in the same time it uses only a small amount of morph database and it's not a competitor of the lab, because it's not comparable with the millions of combinations available in ManuelbastioniLAB. Also it would be nice if the user shows his clearness and good faith promoting the lab and the Open Source phylosophy in his game.
2.1 Is there a way to have two characters in the same scene?
ManuelBastioniLAB is not designed to work on multiple characters in the same scene.
The software is focused on a professional pipeline, where the design of the character occurs in a step completely separated from the animation phase.
Basically you have to think to ManuelBastioniLAB as a separate software, designed to work on one character at time, in order to create the geometry, the rigging, the texture, the clothes and then export it in your folder of characters, ready to be appended in your future final 3d scenes.
There are also many technical reasons for this decision, too long to describe here. To resume in few words: the features are very complex and handle them for multiple characters can potentially create problems, for example the ManuelBastioniLAB morphing system can't be used simultaneously with animated shapekeys and Blender undo system doesn't handle all the lab steps.
2.2 What is the best pipeline to use for create and use characters with ManuelBastioniLAB?
The software is optimised for the pipeline described in the chapter Finalize the character for production scene.
2.3 Why I can't add or delete vertices of characters?
Due to the linear morphing algorithm used to morph the base mesh, the order and the number of vertices can't be altered.
3.1 I'm trying to create my own rigging, but when I use Blender auto weighting function, it returns an error. Can you help me?
The auto weighting function in Blender works only on connected geometries. So You have to finalize the character, split it in pieces with connected topology (body, eyes, teeth, etc..) and then rig each piece separately.
4.1 What should I do to respect the AGPL license for models generated with ManuelbastioniLAB?
If you prefer to use the AGPL license for character generated with ManuelbastioniLAB (so it will be usable only in opensource and AGPL compatible software), you have to include in your package a copy of AGPL license and a copy of this legal notice:
ManuelbastioniLAB - Copyright © 2015-2017 Manuel Bastioni

If the character includes some original pieces created by you, you can specify them in an additional paragraph of the notice above. Note that to work with the AGPL'd character, your pieces must be released using an AGPL compatible license.
