In case someone missed the link to the full series, here it is:
but with some URL mangling I found that there’s one more:
I also tried 5 and 6, but there’s nothing there 
This series includes almost everything you might need to create a complete game-ready character - model, assets, animations, LODs. I haven’t found any other that complete UE4 character creation tutorial series, even no commercial ones. Usually most of tutorials or paid courses are about separate topics and you have to figure out how to put it all together, shooting yourself in a foot multiple times because what works for one model does not work for another.
Really huge thanks to @Mrpdean for the efforts.
But I wish someone would update the series for the latest UE4 versions. Also it would be awesome to have two versions - one for those who would want to use as few 3rd party tools as possible and get something “quick&dirty” but fully working, and another one - advanced, to push Daz3D -> UE4 pipeline to the edge to achieve the best results possible.
Also, it would be awesome to have an option for using free software, such as Blender etc.
MotionBuilder and 3Ds Max is just not an option for a small startup indie team or a hobbyist.
I would even pay for such a complete Daz3d -> UE4 course. Indiegogo, Kickstarter, just UE Marketplace item - anything! Still, no-one has yet accepted the challenge
