Joint editor - Relevance of end point on a figure-as-a-whole

stitlown

Hi Guys,

I'm reasonably familiar with the Joint Editor tool and fully "get" that for an individual bone there is a "start point" and an "end point" and they both mean something in terms of what the bone is representing.

But when it comes to a whole figure node, when selected, Joint Editor shows both.  The "start point" clearly relates to the figure origin for all transforms.  But I am struggling to understand what the relevance of the "end point" is for this node.  Anyone got any ideas?

As a thought provoker, here is a screen cap of a Predaton LoRes figure.  I am changing the default "start point" from about the neck to the bottom of the bum so that mjcasual's great "drop to terrrain" script can work with a consistent "bury" parameter across multiple sitting figures.  But I do not know what (if anything) I should do with the "end point".

Cheers,  Lx  (hope the pic is "readable").

I suppose you tweak bone, with open tool setting tab, then you can confrim each node orientation, and location .

then Without you align node, or change node orientation values manually, root node end point  simply represent "bone view size scholor" only.

  just pull down end point root,  where You feel correct. . and leave it . without tweaking orientation. to be frankly said, even though you move far away, it may not cause  difference. without you locate end point,  extend - z value.  (it change bone rotation way, opositte side)

even though about daz genesis base fgiure, root node end point often not locate as real center.. (then it not represent real bone axis,, just visual thing,)  but keep orientation value as 0,0,0.

But I afraid,, do you really need to adjust center point (and bone orientation)  with complex posing?  it may easy corrupt symmetly bon rocation for rest pose (zero pose), or add un-necessary orientation, I feel.   

most of case,, adjust center point> then adjust end point (as temp), then align node (it auto change bone orentation, to stick on current end point),

or just move end point, without any orientation, then decide visual node length, then only use orientation manually, and adjust bone direction (and roll).

but when you posing,, it may difficult. I think. bone arrangement need for zero (rest pose) correctly. 

 though I think you already know about joint editor, and how it work.  just afraid. it cause un-expected problem , after you tweaking many.

Thanks for the response.  I understand a little better.
