I need to touch some skinning weights inside a SOP graph.
I tried using a point wrangle but I can't get the syntax for accessing the boneCapture attribute right.
Does anyone know how to write to the boneCapture attribute using vex?
Is there a better way of just flagging a group of points to belong to a different bone?

Disregard. I just found the Capture Override SOP that seems to do exactly what I want

Answering 6 years later because why not.

In case anyone is looking for an answer, as I was, you need to use Capture Attribute Unpack to access the skinning informations in vex

How thanks allot for replying to this after 6 years right before i need the info.
I'm looking to rename my segment from L_* to R_* and capture mirror attribute isn’t working.

It seems that you can't really change or ad bone capture regn names, only the indexes, which doesn’t really help here.

You can use Attribute String Edit to rename the region names within the boneCapture attribute

Just specify the attribute name as boneCapture* or directly as boneCapture.pCaptPath for it to work

Or if you really want to use the unpacked attribute, the region names are stored in a Detail attribute where you can edit them
