MoBu 2009/2010 plugin available for download.

by Seth Steiling » Mon Dec 28, 2009 5:56 pm

The ARENA and Expression plugin for real-time streaming and recording in MotionBuilder 2009/2010 is now available for download.

Please post feedback in this thread.

Download the MotionBuilder plugin package (11.6 MB) and tutorial video (106 MB) from OptiTrack.com. Requires ARENA version 1.5 beta 4 or higher.

For Expression users, the plugin delivers a custom pipeline for streaming bone-based face animation data�perfect for video game asset creation. The free download includes:
� Pre-rigged character head
� Customizable constraint builder script
� Tutorial video (separate download)
� Sample data

The included constraint builder script is designed to be a simple departure point for all users familiar with MoBu, but it does not necessarily represent the perfect solution for all facial mocap cases. If you create new versions of the script that better suit your needs, feel free to post your solutions in this thread for the benefit of other Expression users.

In addition to bone-based animation, the new MoBu plugin package also includes 32/64 bit support, a streamlined plugin UI, alpha support for the Virtual Camera Tracker, and bug fixes. For more information, see the build notes below:

When you say "Face Tracking Support now auto-detects and supports local marker position and single rigid body streaming configurations in addition to normal global marker positions," does it mean the head movement can now be removed?

Do we have to follow a naming convention for the rig face bones to have the exspression face constraint script to work?
