Info for those who want to wrap a bunch of objects at once:
First, Load Wall Worm >Wall Worm Model Tools > Hull Helper
Then select the objects to wrap
Then paste this into the MXS listener:
for obj in (selection as array) do ::WallWormHullOps.hullwrap obj
If you get an error about no property "hullwrap" for undefined or similar message, it means you need to update WW.
