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
