[Closed] spacewarp FFD box

For example m(when they are all animateable offcourse):

$FFD01[4][8][1].controller = (point3_script())

You can directly assign a controller to a points controller property. Be aware the point don’t move in world space, but in obj space with value from 0 to 1 some additional math is needed when you want to connect them too world space dummies for example… if that’s what you want offcourse…

What i want is to make them animatable by maxscript, this is the thing i don’t know how to do.

weird… looks like you can’t

and indeed – ‘animateVertex <node/modifier> <index>’ and animateAll <node/modifier> do zilch.

can you use the modifier version instead of the spacewarp?

Edit: … the only other workaround I can think of is for you to create a few FFD cages you’d typically use, animate those manually, save them to a sort of ‘animated FFD cages’ file, and merge the one you need from that file in your script.

No, I have to use the spacewarp version. It`s one of the requirements

actually, I guess you could mimic a manual animate…

-- THE BELOW CODE DOES NOT WORK, leaving for posterity to ponder "why not?"
  -- select your FFD cage spacewarp here
  subObjectLevel = 1
  max select all
  with animate on at time (sliderTime+1) ( move $ [0,0,0] )
  -- clean up the keys here
-- THE ABOVE CODE DOES NOT WORK
  

Edit: scratch that. shakes fist

It doesnt work. Ive tryed to execute it and this code generates two keys, one in frame 0 ando other in frame 1, but it doesn’t make the points animatable. Any idea of why???

yes – it ends up moving the node, not the control points… sigh

anyway – think I’ve got something, but it’s the usual scarycode. ‘ll post once I’ve got it in a function

thanks for all Zeboxx2, i’ll keep trying it too. If i find any solution, i’ll post it here.

dang there’s gotta be easier ways to do this…

maybe making ‘move’ work on whatever the actual active selection is… or making animateVertex work with the spacewarps…or…

anyway.

sample usage:

  myObj = SpaceFFDBox()
  $FFD_box__4x4x4:FFD01 @ [0.000000,0.000000,0.000000]
  showProperties myObj

    .deformType : integer
    .falloff : float
    .tension : float
    .continuity : float
    .length : worldUnits
    .width : worldUnits
    .height : worldUnits
  false
  animateFFDSpaceWarp myObj
  -- some flickering later
  OK
  showProperties myObj
