Hello,
Ive been playing with the “Fix Gixmo” script for individual objects to reset the XForm but retain the pivot orientation:
rollout fT "fixGizmo" width:117 height:35
(
button btn1 "Fix Gizmo Now!!" pos:[8,5] width:99 height:25
on btn1 pressed do
(
thisNodeParent = $.parent
thisNodeChild = #()
for i in $.children do ( append thisNodeChild i )
--unlink code
$.parent = undefine
for i in thisNodeChild do ( i.parent = undefine )
--fixgizmo2 code
with redraw off
(
temppivot = point transform:(getTransformAxis $ 1) text:tempPivot size:0
ResetXForm $ ; CollapseStack $
$.pivot = temppivot.pos
pivot_rotate_angle= temppivot.rotation
$.rotation *= pivot_rotate_angle
$.objectoffsetrot *= pivot_rotate_angle
$.objectoffsetpos *= pivot_rotate_angle
$.pos=temppivot.pos
$.pivot = temppivot.pos
$.rotation = (quat 0 0 0 0)
ResetXForm $ ; CollapseStack $
$.transform = temppivot.transform
delete temppivot
)
--relink code
$.parent = thisNodeParent
for i in thisNodeChild do ( i.parent = $ )
)
)
createdialog ft
For me it would be even neater if it could be traverse hierarchies within a file (perform this operation on each node in the scene—while preserving the hierarchy)
Ive tried a couple of things (ill work on my attempt and try to post one up)—however my previous attempts seem to work but the orientation is lost (all rest to face 0,0,0—but at least the position remains in place)
Other times its keeps some object-hierarchies in place but throws other out all over the scene. Here’s my recursive attempt—:
(
max select all;
--levels, call select parent 1000 times.
for i = 1 to 1000 do (max select parent)
root = $
............previous code
...
--Traverse the scene graph, storing a reference to each node in nodeList.
fn getArrayOfNodesInTree &nodeList currentNode =
(
append nodeList currentNode
for child in currentNode.children do
(
if child != undefined do
(
getArrayOfNodesInTree &nodeList child
)
--This for loop is the recursion stop. Leaf nodes won't have children,
)
)
selectRoot &roots
roots.count
for node in roots do
(
getArrayOfNodesInTree &nodeList node
)
)
catch --Just one root node.
(
--print "Scene has single root."
getArrayOfNodesInTree &nodeList roots
)
for node in nodeList do
(
resetNodeXform node
)
)
Very frustrating as I am very close to getting it …any clues would greatly help!
Thanks for the reply…
I ve looked at that one…but Ive had trouble running it and i’d really like the practice in writing recursive functions…Im just wondering what I am doing wrong
What trouble have you had running it? Please let me know so that I can correct it. What version of Max have you had issues with? In what sort of cases have you found that it will not run or do what you want?
Thanks for the reply Paul…
The problem Ive had is here:
Installation: Down load PEN_resetXform.mzp and drag and drop it in the Max view port. Then use Customize/Customise User Interface to add all four Reset X Form Macros to you favoit menu or hot key. Macros are found in PEN Tool group.
The main problem is when I download the file I get a .zip extention and after I unzip the download, the only file that is a mzp is “mzp.run” which I drag into the viewport but doesnt do anything? Im using Max 2008 32-bit
[UPDATE} As for my progress it appears that my script works fine…however if some objects vary along their pivots in the “UP” direction…ie…some objects have their pivots up on the Y and others up on the Z…it “realigns” the objects with the Z to where their Y faces up…and it aligns it from the orgins point (0,0,0).
Any Idea how to keep these objects in place?
You need to rename the downloaded zip as .mzp (.mzp is a Maxscript Zip-File script Package). Once you have done that then drag and drop to the viewport as directed.

Ah ya, I think that explorer wants to change the extension when you down load files. I guess it thinks the person who created it wasn’t smart enough. Just change the extension to .mzp as suggested and it will work just fine.
Sorry if I’m barging in after the dust has long since settled on this thread, but here is some code I use to eliminate non-uniform (& negative) scales and combine the object offset transform with the node transform before I pass things down to our exporter.
Because it repairs the transform to any children that are affected you should be able to apply it to all the nodes in your hierarchy regardless of traversal order.
I want to stress ‘should be able to’ …you will want to check your work. Maxscript twiddling of node transforms always give me grief.
.biddle
mapped fn myResetXForm n resetType:#RotScale = (
in coordsys world (
currXform = n.transform
desiredXform = case resetType of
(
#Scale : (n.rotation as matrix3) * (transmatrix n.position)
#RotScale: (transmatrix n.position)
#PosRotScale: (matrix3 1)
#ObjOffset: (n.transform)
)
adjustment = (n.objecttransform * inverse desiredXform)
kidadjustment = (n.transform * inverse desiredXform)
n.objectOffsetPos = [0,0,0]
n.objectOffsetScale = [1,1,1]
n.objectOffsetRot = quat 1
adjust_mod = XForm name:("Reset "+(resetType as string))
addmodifier n adjust_mod
adjust_mod.gizmo = adjustment
for c in n.children do
(
c.transform = c.transform * (inverse n.transform) * kidadjustment * n.transform
)
if (currXform.determinantsign != desiredXform.determinantsign) then
(
norm_mod = Normalmodifier name:"Flip Negated Normals" flip:true
addmodifier n norm_mod
subObjectLevel = 0
)
n.transform = desiredXform
)
)
edit:
Note that it clobbers the object offset, so you can’t simply disable the XForm modifier that is applied to disable the reset effect. That was something I was trying to figure out how to avoid when I ran out of steam.
I will have to see if I can find time to compare that to what I have been doing.
