I think most of Maya users know Comet’s PoseReader. For those of you not familiar with this tool, the description can be found at the author’s website – http://www.comet-cartoons.com / maya.html
I have ported to MotionBuilder only PoseReader plugin, It was useful for me for creating advanced rigs.
The plugin is designed as a node for Relation constraint, all incoming and outgoing parameters have similar values with the original plug PoseReader. The only difference is how to set the transformation matrix for objects. In Maya it was two parameters: matrix live in, matrix pose in. In MoBu node has the input parameters for translation live in, rotation live in, translation pose in, rotation pose in.
Pose In – object which will be read posture, which is the most certain Null object that simulates PoseReader node in Maya. This node is used to specify the coordinate system, in which plugin will read rotation axis of the Live object
Live In – the object to be extracted rotation.
Here’s a hint for the plugin – in channels translation I give local value, and rotation – global.
supported MoBu 2013 (64bit), 2010 (32bit)
Source code is in MCL (Motion Code Library)
20.09.12 – first poseReader release in MoBu
