Back in the day, if it wasn't anything I do too often (like UVmapping) I'd just run small PC programs in VMware Fusion or Parallels running winXP as virtual session. If UV optimization is a big deal, Headus UV Layout might be a handy solution (though not for the occasional user.) I haven't tested either VMware Fusion or Parallels out on Sierra, but they should be up-to-date. Handy for running other creator tools like EasyPose. -K
