Re: [Maya-Python] Maya mouse movement event, mouse dragging direction ?

[Virbhadra Gupta]

Here is sample code. It will give first click value and keeps on giving same 
again so i am unable to know drag direction.

contx = "valueDrag"

def onDrag ():
x = cmds.dragferContext(contx, q=True, ap=True)
print x


if cmds.draggerContext(contx, q=True, ex=True):
cmd.deleteUI(contx)
cmd.draggerContext(contx, dc=onDrag, cur="tumble")
cmds.setToolTo(contx)

Result will be like on mouse drag
All anchor point will come same it give only first point of click.

(2,45,0)
(2,45,0)

[Maya-Python] how to Align Transform of objects without using parent constraint ?

[Virbhadra Gupta]

hey,

suppose i have to child objects child_01 & child_02 both are in 
different hierarchy.

i want to match child_02's world transform (translation & rotation) to 
child_01.

parent constraint is one option but do for lots of objects don't know it's 
a good idea or not.

Other option:

i can query child_02's world transform by xform but how can i transfer it 
to child_01
by it be done by matrix ??

i tried:

matrix_01 = cmds.xform("child_02", q=True, ws=True, m=True)
cmds.setAttr("child_01.worldMatrix", matrix_01, type="matrix")

but it's not working.

[Maya-Python] mesh contains a large number of facets Maya warning ?

[Virbhadra Gupta]

Hello,

I have create one script where i changing display mode to smooth mesh 
preview.

cmds.displaySmoothness(object, divisionsU=3, divisionsV=3, pointsWire=16, 
pointsShaded=4, polygonObject=3)

But some time maya give warning window "mesh contains a large number of 
facets..."
and maya stuck until that window is open.

so i am looking to avoid this warning.

> there is not flags of displaySmoothness or command that i can find 
to avoid it.

> i tried to find out face count of mesh and trying to know what 
is threshold (face count) when maya giving this warning.
   but with each object this count is totally change

ex:  i create polyPlane with 1 face. 
  cmds.polySmooth("polyPlane ", dv=7)
  print cmds.polyEvaluate("polyPlane ", f=True)
  result: 4096
  cmds.displaySmoothness("polyPlane ", divisionsU=3, divisionsV=3, 
pointsWire=16, pointsShaded=4, polygonObject=3)

 and

 one single model it hase more then 50,000 face and still smooth mesh 
preview works fine no warning.

Please can anyone know how can i avoid this ?

[Maya-Python] Re: how to make a progress bar that show Maya are working on it

[Virbhadra Gupta]

First you need to import 

import maya.mel as mel

and your moveButton function will look like this

def moveButton(*args):
listItem = cmds.textScrollList( 'scrollList', q=True, si=True)
# accessing maya Main progreas bar
bar_name = mel.eval('$tmp = $gMainProgressBar')
# creating bar
cmds.progressBar(bar_name, e=True, bp=True, ii=True, status='"Your 
Message...', max=len(listItem))
barCount=0
for item in listItem:
episode = item.split('_')[1]
scene = item.split('_')[2]
shots = item.split('_')[3]
phase = item.split('_')[4]
finalpath =  'B:/PROJECT/JTM03/' + episode + '/' + 
phase.split('.')[0] + '/'
newFileName = 'JT_' + episode + '_' + scene + '_shot' + 
shots.split('SH')[1] + '_ani.ma'
srcfile = finalpath + item
dstdir = 'V:/J_Team/3D/Shots/' + episode + '/' + scene + '/shot'+ 
shots.split('SH')[1] + '/'
finaldst = 'V:/J_Team/3D/Shots/' + episode + '/' + scene + '/shot'+ 
shots.split('SH')[1] + '/' + newFileName
if not os.path.exists(dstdir):
os.makedirs(dstdir)
shutil.copy2(srcfile, finaldst) 
# adding progress in bar
cmds.progressBar(bar_name, edit=True, step=barCount)
barCount+=1
# Ending bar
cmds.progressBar(bar_name, edit=True, endProgress=True)

[Maya-Python] Parent Constraint Issue when removing constraint

[Virbhadra Gupta]

Hello, i am trying to remove parent constraint using parentConstraint 
command.

but constraint created by skipping any Tran or Rot attrs 
cmds.parentConstraint(obj1, obj2, rm=True) won't work why ??

am i doing something wrong ??

here is sample code and error:

# Creating two objects
box1 = cmds.polyCube(n="box_01")[0]
box2 = cmds.polyCube(n="box_02")[0]

# Creating parent Constraint only for Translation
cmds.parentConstraint(box1, box2, mo=True, sr=["x","y","z"])

# checking if "box_02" have parent constrint
consObj =  cmds.parentConstraint(box1, q=True, tl=True)

# removing constraint
cmds.parentConstraint(consObj[0], box2, rm=True)

###

#Error: RuntimeError: file  line 1: Cannot edit object with no 
constraint.
