Using MotionBulider and Python to create a Take Renaming Tool

I’ve used Take Renaming tools in the past and I’ve always found them to be an amazing time saver, so when I sat down to think about what I would like to learn next in my Motionbuilder Python Scripting adventure I knew that writing my own Take Naming Tool would be a lot of fun.

This experiment lead me to do a lot of google searching, thankfully I was able to sift through a ton of links and forums to find what I needed and along the way learned a lot through trial and error.

Here is a quick demo of the TakeReName_v1.0 tool.

Below I will spot light what was new to me, going quickly over searching for a string and dealing with letter case as well as replacing strings.

The entire Take Renaming (TakeReName_v1.0) script will be posted at the very end, or if you would just like to skip all that and down load the script than you can find it here. 🙂

I used the Regular expression operations to do the brunt of the work and you can read more about the re module here. For this post we will simply import the re module and move onto the functions “findall”, “IGNORECASE” and how we will swap words/characters within strings.

Importing the re module is easy enough:

from re import *

Below we have two example of  the “findall” function that only have 1 small difference – “IGNORECASE”. You can find more information on “findall” here.

##this line is used only for this example
eFind.Text = "Take 001"

## Findall Example that is case sensitive
## On every Take in our scene
for take in FBSystem().Scene.Takes:
    ## search the take name for our desired string and if found make have that take become selected
    if findall(eFind.Text,take.Name):
        ## Select the take
        take.Selected=True 
    else:
        ## have the take become deselected if the desired string is not found make within the take's name 
        take.Selected=False

## Findall regardless of letter case using IGNORECASE
## On every Take in our scene
for take in FBSystem().Scene.Takes:
    ## search the take name for our desired string and if found make have that take become selected
    if findall(eFind.Text,take.Name, IGNORECASE): ##IGNORECASE 
        ## Select the take
        take.Selected=True
    else:
        ## have the take become deselected if the desired string is not found make within the take's name  
        take.Selected=False

Below here is an example of replacing the original text with our newly desired text. I tried a number of methods (starting with this one), but they would fall short when it came time to test with using my TakeReNamer tool’s “Ignore Case” option. After many searches and reading many forums I stumbled upon this link.

## If selected rename that takes to the desired string within the "Replace" field
for take in FBSystem().Scene.Takes:
    if take.Selected == True:
        ## Deal with the "Find" field so that the string is not case sensitive
        lProcessFields = compile(escape(eFind.Text), IGNORECASE)
        ## Witihin our Current Takes Name - Substitute our "Find" field string with our "Replace" Field string
        lReName = lProcessFields.sub(eReplace.Text, take.Name)
        ## Rename the take to the new Take name
        take.Name = lReName
        del lReName

Here is the full script:

from pyfbsdk import *
from pyfbsdk_additions import *
from re import *


##labels
lFind = FBLabel()
lReplace = FBLabel()

##editable fields
eFind = FBEdit()

bAsSuffix = FBButton()

bSelTakes = FBButton()
bRename = FBButton()

##Determine if "Ignore Case" is selected and then search all takes for the desired input string
def SearchAndSelctTakes():
    ##Make Sure no takes are already selected
    for take in FBSystem().Scene.Takes:
        if take.Selected == True:
            take.Selected=False
        else:
            pass
    ##Ignore Case        
    if bIgnoreCase.State == 1:
    ##Find all takes that match the text inputed in to the "Find" field of our tool window        
        for take in FBSystem().Scene.Takes:
            if findall(eFind.Text,take.Name, IGNORECASE):
                take.Selected=True
            else: 
                False
    ##Case Sensitive
    else:

Overall the tool was a lot of fun to write. I wish the input fields were a little more forgiving to use, sometimes I would have to hit the ReName button twice – first time deselected the field I was last typing in and the second click would actually run the renaming script it self. this is more of a MotionBuilder python UI thing.
