Geta-Ve… Thanks for your synapses here mate… This is (naturally) proving a little more challenging than I first thought. The reason for the softer look is that when I exported the obj from ZB it kinda shrunk it as if deflating the normals a bit… Dunno why
The battle is now officially over and ZB and I are like best buds again… The system for retopo on a hi res mesh with mouth cavities etc is not a 1 click automagic solution. It requires a little tweeking and patience but is definitely worth it:buttrock:
Anyways… I’ll be moving ahead with this project now that my first technical hurdle is behind… More soon
Here’s a shot of the all quad retopo’d mesh

well worth the effort for this workflow
