The new Digital Human in UE4 is amazing. The important thing is: How do we utilize it to improve our characters?
Can i just copy and paste the materials from the Digital Human to my character?
You won’t be able to copy over the files directly if you’re not using 4.20, but you could copy/paste the material network or rebuild it yourself if in an older version. It uses a lot of features that probably won’t be beneficial to a standard game character(hair blur, post-process materials for scattering, etc), but 4.20 has the dual-lobe specular and eye shading improvements, so you could possibly compare between the new materials to the old Twinblast setup and see if they changed anything. I haven’t looked at the new materials yet, but I wouldn’t be surprised if they also include things not suitable for standard game characters.
There’s a whole guide for it: Digital Humans | Unreal Engine Documentation
