Top 30 committers 2023

While the year runs on its last legs, it’s time to celebrate another fantastic Blender year – made possible by the community of contributors at

Below is the list of top committers to the Blender project in 2023. The number of commits obviously doesn’t mean much, but it’s a neutral metric to put a limelight on people who made Blender possible last year.

Miguel Pozo (194, Spain, dev grant)

Miguel is part of the EEVEE & Viewport module and has been an important part of the EEVEE Next development project.

Falk David (220, Germany, BI employee)

Falk’s main project for the year has been leading the Grease Pencil V3 rewrite project.

Harley Acheson (263, Canada, dev grant)

Harley has an eye for details. He improved and fixed areas in Blenders UI this year, giving users a more polished and focused experience. He also contributed to a better UI font system again, with a new default font and support for more languages.

Sergey Sharybin (283, Russia, BI employee)

Sergey contributed to motion tracking, Cycles rendering, and sculpting. In particular, light and shadow linking was a feature many people have been waiting for!

Julian Eisel (298, Germany, BI employee)

Working on Blender’s user interface, this year Julian focused on the asset system and the new asset shelf. He also contributed significantly to a new developer documentation platform.

Germano Cavalcante (315, Brazil, dev grant)

Germano is part of the triaging team and also helps with bug fixing. He also made significant improvements to the transform system, including the base point snapping feature.

Brecht Van Lommel (316, Belgium, BI employee)

Among many other areas, Brecht worked on Cycles this year and contributed significantly to the developer website backend.

Clément Foucault (331, France, BI employee)

Clément worked on a major rewrite of the EEVEE realtime renderer to take advantage of modern GPU features and to add new features like screen space global illumination and displacement.

Bastien Montagne (402, France, BI employee)

Bastien is an owner of the core module, his main concern is to keep Blender files and overrides working.

Jeroen Bakker (429, Netherlands, BI employee)

Jeroen is part of the rendering team, the go-to person for everything viewport and GPU related. He worked on Vulkan support this year.

Jacques Lucke (489, Germany, BI employee)

This year, Jacques worked on geometry nodes features including baking, simulations, and the repeat zone. He also improved menu search, and moved most of Blender’s C code to C++.

Hans Goudey (1383, USA, dev grant)

Besides contributing various geometry nodes features like node tools and asset integration, Hans enjoys refactoring Blender to improve performance and modernize code. This year he finished a large change to Blender’s mesh storage.

Campbell Barton (2017, Australia, dev grant)

Campbell contributes to nearly every core module in Blender. This year he worked on Wayland support and the extentions platform project.

I wish all of the people above and everyone who contributed to Blender a healthy and happy 2024!
