Qualification of Motionbuilder
Products Version Software Date
MotionBuilder | MoCap 6.0 20041008

File Compatibility :


Motionbuilder: In 6.0, the .fbx file format has been updated completely. As a result, loading .fbx files created in MotionBuilder 6 into older versions of MotionBuilder is not supported. If you want to open .fbx files created in version 6.0 in older versions, navigate to the diretory where you have MotionBuilder installed (such as C:\Program Files\Alias\MotionBuilder6\) and run the FbxConverterUI application found in the "bin" folder. This application allows you to convert the basic assets in a 6.0 .fbx file, such as bones with fcurves, into 5.x .fbx files so you can open them in older versions of the software.



The FBX converter application can convert files to and from the FBX, DXF, 3DS, and OBJ formats. The assets supported for each type of conversion vary. If you want to convert OBJ, DXF, or 3DS file formats, refer to the tab for each specific file format in the FBX Converter interface. The tab for each file format includes check boxes that let you select the type of objects you want to convert.

If you are converting .fbx files from version 6.0 to 5.x versions, the following assets can be converted:

  • Geometry (mesh, Nurbs, patches) 
  • Deformation (skin, shapes)
  • Models (nulls, geometry, bones, cameras, lights)
  • Animation, Degrees of Freedom

Graphics Cards and Driver Versions


MotionBuilder is qualified for the following graphics cards using the specified driver, with the listed Operating Systems.

Important: Graphics drivers are usually different for different Windows operating sytems. Alias has tested only drivers listed under each OS. While it may be possible to use MotionBuilder successfully on earlier or later drivers, Alias cannot guarantee their performance or behaviour. If you encounter problems with a driver, we strongly suggest that you contact the graphic card vendor to report your problem.

General Configuration
  • It may be possible to successfully use MotionBuilder with a non-qualified or partially qualified configuration, but support and maintenance programs will be subject to the Alias Support services guidelines.
  • The configurations shown are subject to change, and additional qualified configurations may be added after qualification testing has been carried out.

Windows XP Recommendations
Windows XP does not automatically install OpenGL drivers. You must access the Web site of your graphics card manufacturer and download the most recent Windows XP OpenGL driver(s).

Mac OS X Recommendations
Only MotionBuilder and MotionBuilder Professional run on Mac OS X. Alias MoCap and Alias OnLine run on Windows XP only.

Macintosh computers come with a single button mouse. It is recommended that you install a USB two-button or three button mouse for use with MotionBuilder.

To emulate a three-button mouse, use the following keyboard and mouse combinations.


Some Macintosh keyboards only have one Delete key as compared to computers running the Windows operating system. If you cannot delete using the Delete key, press Shift-Delete or Backspace.


Nvidia GeForce256, GeForce2, GeForce3, GeForce4 series
There are many cards based on GeForce256, GeForce2,  GeForce3 and GeForce4 chipsets. Nvidia and Alias do not recommend these cards for use with MotionBuilder as you may experience various refresh, display and stability problems and inadequate performance.

We suggest you choose from Nvidia's workstation cards instead, such as the Quadro families which are much better suited to high-end 3D packages such as MotionBuilder.
