I can't begin to tell you how much research I put into Newtek's products back in the 90's :) The ability to program custom apps within Lightwave astonished me into buying it, but it was just too damn expensive for my meager hourly wages at the time.
I know I post here a lot, and say goofy things, but I can't thank you enough for sharing your hard-won knowledge with other Lightwave users. I never dreamed mocap could be used on this program, even recently! Almost makes me wanna jump into programming again!

The motion capture adaptation is a custom program I made within Lightwave so that I can use mocap motions on my custom rigs fairly quickly (mocap skeletons aren't ideal for character animation because they are not designed well for it). Then I use Lightwave's IKBooster animation toolset to make the saved motion able to be relative to the character's current position/rotation in 3d space.
The sad thing is, Lightwave has had these kinds of tools for over a decade... unfortunately Newtek's marketing team sucked horribly and they failed to release example usage content/documentation. Part of that was because the creator of the functionality had trouble speaking english and therefor the other developers had a hard time with creating a manual for it. IKBooster had *zero* documentation paired with it when it was released... such a shame (and a lot of it is STILL undocumented to this day!).
