Best Free and Open Source Alternatives to Autodesk MotionBuilder

Autodesk, Inc. is an American multinational software company that makes software products and services for the architecture, engineering, construction, product design, manufacturing, media, education, and entertainment industries. It bills itself as a “… leader in 3D design, engineering and entertainment software”.

The company was founded in 1982 by John Walker, who was a joint developer of the first versions of AutoCAD, the company’s best known software application. Autodesk is listed on the Nasdaq stock exchange, it has over 11,000 employees, and is headquartered in the San Francisco Bay Area.

While Autodesk develops many high quality applications they are proprietary software. And the vast majority of their products are not available for Linux. This series looks at the best free and open source alternatives.

MotionBuilder is 3D character animation software. The software is designed for virtual cinematography, motion capture, and traditional keyframe animation. Capture, edit, and play back complex animations.

MotionBuilder is available for Linux but it’s proprietary software. We recommend the best free and open source alternatives.

1. Blender

Targeted at media professionals and artists, Blender can be used to create 3D visualizations, stills as well as broadcast and cinema quality video, whilst the incorporation of a real-time 3D engine allows for the creation of 3D interactive content for stand-alone playback. Blender has a huge variety of uses including modelling, animating, rendering, texturing, skinning, rigging, weighting, non-linear editing, scripting, compositing, post-production and much more.

Blender has a robust feature set similar in scope and depth to other high-end 3D software.

2. Bforartists

Bforartists is a complete 3D suite to create 3D content. It offers you the full 3D art pipeline to create game graphics, prerendered movies and stills. From modeling, sculpting, texturing, rigging, animation, rendering, up to post processing.
