Tools

Set project button!

Nice little tool which looks for you ‘scenes’ folder and sets the project to that location:


import maya.cmds as cmds
import maya.mel as mel
import maya.OpenMaya as om
 
def setProj():
    # find directory
    currentDir = cmds.file( query = True, location = True )
    # dicect directory and set project
    try:
        projectDir,garbage = currentDir.split( 'scenes' )
    except:
        return om.MGlobal.displayError( 'You need to have you file in a project folder structurte first' )
    mel.eval( 'setProject ' + '"' + projectDir + '"' )
    om.MGlobal.displayInfo( 'current project set to : ' + projectDir )
    del projectDir
    del garbage
setProj()

Zeroing out. Or in.

Today I wrote a little tool that simply groups whatever you have selected, for the purposes of cleaning up transforms. Also works with multiple objects selected and groups them all under a group in the same worldspace as the first selected object.
Grab the code here and place it on your shelf.

import maya.cmds as cmds
import maya.OpenMaya as om

grpList = cmds.ls(sl = True)

parentObj = cmds.listRelatives( grpList[0], parent = True )
cmds.group( em = True, name = grpList[0] + '_Zero_GRP' )
cmds.parentConstraint( grpList[0], grpList[0] + '_Zero_GRP' )
cmds.delete( grpList[0] + '_Zero_GRP_parentConstraint1' )
cmds.scaleConstraint( grpList[0], grpList[0] + '_Zero_GRP' )
cmds.delete( grpList[0] + '_Zero_GRP_scaleConstraint1' )
cmds.parent( grpList[0], grpList[0] + '_Zero_GRP' )
try:
    cmds.parent( grpList[0] + '_Zero_GRP', parentObj )
    om.MGlobal.displayInfo( grpList[0] + ' now has a group above it' )
except:
    om.MGlobal.displayInfo( grpList[0] + ' has no parent object, grouped in world space' )

cmds.select( grpList[0] )
newParent = cmds.listRelatives( parent = True )
listEndNumber = len(grpList)
remainingObj = grpList[1:int(listEndNumber)]

for i in remainingObj:
    cmds.parent( i, newParent )

om.MGlobal.displayInfo( grpList[0] + ' now has a group above it' )

 

Naming and renaming

During the last job I was on, we were receiving rigs from another company.
These rigs did not always match our hierarchy and naming conventions, so, part of my job was to recompile these rigs to match our conventions. One common and potentially time consuming job was the renaming of control curves.
We would receive them with naming conventions along the lines of ‘*_Ctrl_01’, ‘*_Ctrl_02’ and so on.
Renaming every control in the rig is neigh on impossible, so I wrote a script to do so!
The script I wrote was smashed together with no time for optimization but now with a little time on my hands I have rewritten it to be user friendly and fast.
Here it is, have a look!

import maya.cmds as cmds

selection = cmds.ls( sl = True)

for i in selection:
    shape = cmds.listRelatives( i, shapes = True )
    if shape == None:
        print 'No shape for ' + i + ', aborting.'
    else:
        try:
            a,b = i.split('_Ctrl')
            cmds.rename( i, a + b + '_Ctrl' )
        except:
            print 'No Ctrl in name of ' + i

Saving time

I spent today putting finishing touches on a script that saves a new version of the current scene. and a button icon to go with!

Cluster tool

I wrote a bit of code that will create a cluster on polygon geometry regardless of selection type, eg face, edge or vertex. Speeds things up a little.

import maya.cmds as cmds
def makeCluster():
	selection = cmds.ls(sl=True)
	for i in selection:
		string = str(i)
		try:
			object,selected = string.split('.')
			sel,CVnum = selected.split('[')
			if sel == 'e':
				verts = cmds.polyListComponentConversion(selection,fromEdge=True,toVertex=True)
				cmds.select(verts, r=True)
			print 'passed edge'
			if sel == 'f':
				verts = cmds.polyListComponentConversion(selection,fromFace=True,toVertex=True)
				cmds.select(verts, r=True)
			print 'passed face'
			if sel == 'vtx':
				print ' no conversion needed'
			print 'passed vtx'
		except:
			print 'object selected'

	cmds.cluster()
makeCluster()
