Would a character proficient at matrix sculpting be skilled at Software [VR Sculpting] or Artisan [VR Sculpting]?

I've been through Unwired and the core book several times and can't seem to find an answer to this. My instinct would be Artisan, on the grounds that a skilled programmer could easily be incompetent at sculpting nodes and icons, but the listed specialties for Artisan suggest it's for more tangible arts.

That would probably be Computer (Edit), because the Edit program is the universal graphic design software.  Or I suppose it could be done with a Software (VR Sculpting) test, if you're not using a program to do it but instead building the graphics code by yourself.

Thank you.
