The software is written in [[Python (programming language)|Python]] and works on all the platforms supported by Blender: Windows, macOS and Linux.

ManuelbastionLAB provides two different base meshes for male and female models. Each model respects the fundamental requisites of a professional mesh, as defined by the author:<ref>{{Cite web|url=https://mb-lab.readthedocs.io/en/latest/base_char.html|title=Base characters in Manuel Bastioni Lab|work=mb-lab.readthedocs.io|access-date=2019-10-31|archive-url=https://web.archive.org/web/20191031092517/https://mb-lab.readthedocs.io/en/latest/base_char.html|archive-date=2019-10-31|url-status=live}}</ref>

* Optimization for [[subdivision surface]]s.

* No triangles.

== Current stage of development ==

The project has been discontinued abruptly by Bastioni,<ref name="CE-shutdown">{{Cite web|url=https://www.blendernation.com/2018/11/26/manuelbastionilab-character-editor-shuts-down/|title=ManuelBastioniLAB Character Editor Shuts Down|date=November 26, 2018|website=BlenderNation|access-date=November 1, 2019|archive-url=https://web.archive.org/web/20190607030328/https://www.blendernation.com/2018/11/26/manuelbastionilab-character-editor-shuts-down/|archive-date=June 7, 2019|url-status=live}}</ref> after the release 1.6.1a, which was not compatible with Blender 2.80.{{cn|date=October 2019}} Bart Veldhhuzien indicates Bastoni attempted unsuccessfully to raise funds and then chose move quoting Bastoni as saying: "I’m sorry, I did my best, but I cannot continue the development of the lab. I will use Blender as artist, since Blender and its community are part of my life."; and "I realized that the lab community size is not enough to support a so expensive project".<ref name="CE-shutdown"/>

In December 2018, a new repository, based on last Bastioni's version (1.6.1a), aiming at Blender 2.80 compatibility, has been opened on GitHub with project name MB-Lab.<ref name="Fork1">{{Cite web|url=https://github.com/animate1978/MB-Lab|title=MB-Lab GitHub clone|website=github.com|access-date=2019-01-31}}</ref>
