Where is the live link plug in for motion builder for 4.19?

it says from the doc

  1. inside the plugins
  2. under anim ->enable
  3. nav to the engine istall location and Engine\Extras\MayaLiveLink
  4. Unzip it (would recommend doing it to another folder)
  5. Copy to your version of maya, the install folder, and put it in the plugins folder (if you have maya open will need to turn if off for it to detect the plugin)
  6. enable the plugin in maya
  7. to do so, in maya
  8. windows(from the top bar)
  9. settings/preferences
  10. plugin manager
  11. and find the live like plugin in there,
  12. if you don’t see it you will need to browse for it, as it don’t always auto detect it
  13. then after that, hit auto-load and loaded (as if it don’t autoload the next time, might have to do it once or twice, which is a maya thing)
  14. You will see it kick in at the mel scrip console line.
  15. then in UE4 ->menu bar-> window->live link
  16. add → message bus source -? maya live link
  17. and the live link on maya should turn green
  18. Now your playing with fire.

well they talk about it here being (as from the doc), download and in the engine files some where.
