  I finally discovered that.
  I thought i could be "cute" and include the .inc file right away and thus make

  So, thanks.
  Now i have an #if..#end problem that is bugging me:

//        NOTE: Change output filename in Tank.INI for output scene name
//              Save change, then run Tank.INI
