[Closed] Skin Modifier Issue And Alternative

i make a little check, this is the synthetic code:

 FOR LOOP
 ...
 theskin = Skin()
 theskin.rigid_vertices = false
 select obj						
 addModifier obj theskin
 max modify mode
 checkmod = modPanel.getCurrentObject()
 format "CURRENT: %
" checkmod
 if checkmod==undefined then error.e -- make a "stop error"
 skinops.buttonInclude theskin
 ...
 

Listener:

 CURRENT: Skin:Skin --loop1
 CURRENT: undefined --loop2
 

the problem is on second loop, the checkmod = modPanel.getCurrentObject() return undefined but is not possible… why max crash in the modifier pannel ???

I really don’t know what your trying to do, from what i can make out your trying to add bones to a skin modifier. Something like this:

fn addBoneToSkin skinMod bones =
(
 -- we check the modifier is valid
 if classOf skinMod == Skin do
 (
  -- set the rollout panel
  max modify mode
  modPanel.setCurrentObject skinMod

  -- add the bones
  for each in bones do
  (
    if each != undefined do
    (
      skinOps.addBone each 1
    )
  ) 
 )
)

To load weights onto a vertex you need an array of bone IDs reflective of the bone list in the skin modifier, and an array of weights – that equal one. If you want every vertex set to the first bone with a weight of one:

fn setDefaultWeight skinMod =
(
 local skinObj

 if classOf skinMod == Skin do
 (
  max modify mode
  modPanel.setCurrentObject skinMod

  -- we get the dependent mesh from the skin
  skinObj = (refs.dependents skinMod)[3]

  -- we should check if there are bones to skin
  if skinOps.getNumberBones skinMod >= 1 do
  (
    -- we set the weight
   for v = 1 to skinObj.verts.count do
   (
    skinOps.ReplaceVertexWeights skinMod v 1 1.0 
   )
  )
 )
)

THANK for answer, but i found the problem:
i have utilized the ProgressBar (ProgressStart “”; progressEnd(); progressUpdate() ) but i put two ProgressStart “”, the second bar make some problem with modify mode of max, in fact all work if i write:

 .
..
...
	theskin = Skin()
	theskin.rigid_vertices = [b]false[/b]
	select obj
	[i]--resumeEditing()[/i]
	addModifier obj theskin
	max modify mode
	modPanel.setCurrentObject theskin
 
	checkmod = modPanel.getCurrentObject()
 
	format "current_modifier: %" checkmod
	if checkmod==undefined do
	(
		format "--> Error, try to resume -->"
		resumeEditing()
		select obj
		max modify mode
		modPanel.setCurrentObject theskin
		checkmod = modPanel.getCurrentObject()
		format "current_modifier: %" checkmod
		if checkmod==undefined do return undefined
	)
	format "[b]
[/b]"
	skinops.buttonInclude theskin
...
..
. 

from listener:

CURRENT: Skin:Skin
CURRENT: undefined ERROR, TRY TO RESUME CURRENT: Skin:Skin
CURRENT: undefined ERROR, TRY TO RESUME CURRENT: Skin:Skin
CURRENT: undefined ERROR, TRY TO RESUME CURRENT: Skin:Skin
etc…

i delete the progressBar and all work:

CURRENT: Skin:Skin
CURRENT: Skin:Skin
CURRENT: Skin:Skin
CURRENT: Skin:Skin
etc…

But i have windows7 x64 and if the script run for more than 7 seconds 3dstudio sleep until the script stop… with progressBar windows have a lot of “output” from 3dstudio and don’t sleep… but the modify panel don’t work…

So i must delete the progressBar dialog and all work correctly

NO SORRY, the problem isn’t the ProgressBar…
i make the simple function:

    function AssignWeight obj weight SkeletonData=
    (
    	try
    	(
    		max modify mode
    		select obj
    		subObjectLevel = 0
    		Local theskin = Skin()
    		addModifier obj theskin
    		Local theskin = obj.modifiers[#Skin]
    		subobjectLevel = 1
    		modPanel.setCurrentObject obj.modifiers[#Skin]
    		subobjectLevel = 1
    		skinOps.addbone theskin (getNodeByName SkeletonData[1].Bone.name ) -1
    		update obj
    		obj.selectedVerts = #{1..obj.numverts}
    		skinOps.resetSelectedVerts theskin
    		update obj
    		subObjectLevel = 0
    		deselect obj
    	)
    	catch getCurrentException()
    )
    

the script don't make error, but the bone aren't added in the list and when i clic on object the 3dstudio crash !
I don't undertand why... all is correct.
If i use the only function:

 addModifier obj theskin

without all other "skinOps." function, 3dstudio don't crash... the problem is on "skinOps.addbone", it don't work !

Roughly, I’m not at my desk…

fn addSkinNBones obj boneNames =
(
if obj != undefined do
(
 local skinMod, bone

 addModifier obj (skin())
 skinMod = obj.skin

 max modify mode
 modifyPanel.setCurrentObject skinMod

 for each in boneNames do
 (
  bone = (getNodeByName each)
  
  if bone != undefined do
  (
    skinOps.addBone skinMod bone 1
  )
 )
)
)

[QUOTE=eek]
I put my script in a essential version, the script apply the skin() modifier and if you clic ok in the queryBox the script add the bones in the skins witout error.
BUT:
when i clic on box objects the 3dstudio crash !?! WHY ???
