motiontrail arclength

[kevco...@gmail.com]

Hey guys,

is there any way to get the arclength of a motion trail?

the motiontrail shape doesn't have a 'worldSpace' attribute, so I can't plug it into a curveInfo node.

Thanks

or is there any other way of getting a curve from keyframe data, but still keep it live? So if I adjust some keys in the graph editor, the curve updates.

or how about just calculating distance at the current time from translation fcurves?
