My "general goal" is the make the makehuman characters a bit more easy to use in Unreal, so I made this tutorial http://www.makehumancommunity.org/wiki/Documentation:Saving_models_for_Unreal_Engine_and_how_to_import_them_there and I also made a Blender tool to "copy" the MH shape keys into blender, when importing into blender, so these shape keys can be used to customize the characters in Unreal. For the last part I made "MHC - UE4 Generic Character customization for MakeHuman, and other characters" http://www.makehumancommunity.org/wiki/Documentation:Unreal_MHC#Customization.
The general idea is that you should be able to make as many characters as you like for Unreal. So you will be able to populate your games with random characters high quality characters. For this to work there is now only very few missing elements. One of those would be a way to transplant a MetaHuman head to a makehuman body! I already managed to do this, but I think that it would make a lot of sense if we could make this work with a baked/lower quality of the textures - that is it should be possible to "swap" the MetaHuman head materials and hair, directly to the makehuman character... and then switch to the metahuman head for Lod0 closeups. Just as one example of what could be.
( This is an example of MH with a metahuman head - not perfect yet: viewtopic.php?f=14&t=18462&start=60#p53940 )
In this way you will get the best of both worlds. On the same node, you could also transfer some of the MH shape keys to the MetaHuman head, as you could transfer the "live link" shape keys to the makehuman heads - giving people the "sliders" what they want!
If you take a look at what people want to do it appears that MakeHuman can deliver both the body and the "morph targets", in one way or an other (See these requests here https://www.youtube.com/watch?v=ys3JivS-iXU&t=3990s )
Anyway; I would be very happy to help out in what ever way I can - within the limits of my time. Perhaps I can make some tutorials and I am definitely going to get the Unreal customize tool working.
