Sorry there @Printninja, I think your mistaken, it DOES work with pinegrow 3 AND 4, so I’m ASSUMING,
Pinegrow 5.
Your reference is correct at the time of posting (oct 2017) and says it merges two threads,
BUT,
mine is NOVEMBER 2017 (wow, a whole 4 weeks later) and for some reason… wasn’t merged, so yeah, Confusing.
No need to go all retrograde on version installing, it’s all good 
see here
and here
So the link sending is for those who have purchased it
and it is for
ANIMATOR PRO…
which is different to ANIMATOR … which was free
So there you go @ash786 I hope that clears things up.
if I’m wrong, I stand to be corrected, but
the info is here
http://animator-pro.mhdaljuboori.me/#how_it_works
and here are some screen shots of Animator PRO installed in my Pinegrow Version 5.
But… I’ve not done it any justice yet.
SO I MIGHT play with it later
SO here it is listed in my plugins,
(Note FESTIVE Santa hat for maximum mirth and Merriment)
Activating it requires the automatic installation of waypoints
and takes place when you ACTIVATE the plugin
like this
and TADA!! here it is, installed in my PineGrow 5.
oh! you have to click on the image to see it full size WITH the animator pro bit. weird.
SO, if I’m missing something, sort me out
