Hello,

In this thread [www.sidefx.com], I learned how to remove the end characters of a string using VEX.


How would I go about deleting the beginning characters of a string?

I have a KineFX rig in my scene and, as an example, I want to rename the name attribute of my joints from this:

ManSkeleton_Complete:Joint_1
ManSkeleton_Complete:Joint_2
ManSkeleton_Complete:Joint_3

to this:

Joint_1
Joint_2
Joint_3


Any help would be appreciated.

Thanks!

you could try split()

and use the string ":" as the separator

Hey thanks Mike, that worked great. I have exactly the same issue as Nico. The characters are coming from Maya with a namespace at the front of every joint. I need to remove that namespace so the constraints and hand controls work.

This is the code in an attribWrangle that worked for me (got the idea for the code from: https://vimeo.com/193825912):

Now the problem is that I can't get all my edited animation back onto the character using the bone deform. Removing the namespace is creating a difference somewhere that stops the animation... If I figure it out, I'll post here.

You could also just use the Attribute String Edit SOP:
- Enable Detail for good measure
- Editor > From = ManSkeleton_Complete:*
- Editor > To = *
