Sorry that my English is not very good, I used the fbxSkinImport node to import a skinned mesh body, hoping to read the skin information of the mesh body in AttribwrAngle, which is called the boneCapture attribute in Houdini. It seems that MY operation cannot access this attribute, I would like to ask how to do the hidden access To this property right here

you need to use Capture Attribute Unpack SOP first to convert such attribute to set of array attributes you can edit in VEX for example and then Capture Attribute Pack SOP to convert it back
