This RL vid on Youtube exactly as outlined:
https://www.youtube.com/watch?v=1AnfSUVWklsI've tried numerous poses/anims in Daz from Daz's own to several high end 3rd party assets, all with same results, no import into UE4 unless I follow the previously outlined steps which weren't documented anywhere.
On another note, there are numerous issues with bringing poses/anims from Daz to CC3+ using Transformer.
I've been importing/exporting to UE4 from CC3 and Daz for several months now. Only when I bring 3dXchange into the mix does the process break.
