bake world position to vertex color

This script bake the vertex position in world space into the vertex color. Just select the objects and run the script

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


sel = om.MSelectionList()
om.MGlobal.getActiveSelectionList(sel)

vertexColorList = om.MColorArray()
vertexIndexList = om.MIntArray()

dagPath = om.MDagPath()
component = om.MObject()


iter = om.MItSelectionList(sel)
while not iter.isDone():
    iter.getDagPath( dagPath, component )
    meshFn = om.MFnMesh(dagPath)
    meshIter = om.MItMeshVertex( dagPath, component )
    index = 0
    while not meshIter.isDone():
        
        point = meshIter.position(om.MSpace.kWorld)
        color = om.MColor(point.x,point.y,point.z,1)
        vertexColorList.append(color)
        vertexIndexList.append(index)
        index = index +1 
        meshIter.next()
        
    
    meshFn.setVertexColors(vertexColorList,vertexIndexList )    
    iter.next()

Maya Messanger

this 2 scripts allow to send and read messages without leaving maya.
Its possible to write notes for a single shot and read only the messages
for this shot.
Its also possible to mark messages as read, so you just see the new messages.

So every teammember have to put the scripts in his  Users\User\Documents\maya\2012-x64\scripts
or another script directory.
 In both Scripts:
 Fill the Variables mySelf, teamMembers, inputStorePath
mySelf and teamMembers with only 2 characters, if you have 2 Persons with the same initials
use of capital and small initial letters
Fill the Input StorePath with a Path (we use it with dropbox folder), anFtp server mounted as a drive, or a FileServer
end the path with /

like this:
teamMembers =('RF','NL','MH','CB','PK')
mySelf = 'RF'
Path='C:/Users/RF/Dropbox/Hermit/Software/TXTmessages/'

to Use the scripts:
execute the rf_exeRead.py or rf_exeSend.py script for wrting or reading.
You can create shelf buttons with this two scripts.

all Scripts together in a zip archiv
4 scripts in a zip folder

seperated Scripts:

create playblast in h264 mov

This script creates a playblast and auto convert it as a h264 mov

2. #
3. #    Export a PlayBlast with Handles and Convert the Avi to a h264 mov File
4. #        
5. #    function createH264PB(path to the nuke.exe, framerate, handles,width, hight)
6. # 
7. #    if the framerange doesnt match with your scene framerate ,the script will not run
8. #
9. #    the mov is in the images folder
10.  
11. import rf_playblast
12. rf_playblast.createH264PB("C:\Program Files\Nuke6.3v1\Nuke6.3.exe",25,10,1280,720)
