Hi there, 

I like to ask if I'm doing things the best possible way, or there are better ways. Because I run into a bit of hassle... 
Mainly, I'm exporting Kevin to Blender with the GoB plugin, and in Blender the Blender Addon for CC. 
Everything grate. Then I export Kevin, and 3D Scan I have from 3DScanStore, to Zbrush to wrap with Zwrap. 
Also everything fine here. Then I just import it back to Blender, and Add the wrapped CC4 topology as a shape key via JOIN AS SHAPES. 
Also great. Then I just move it to the top of the list of all the shapes, and delete the BASIS one. 
And then I export it to CC4 via the plugin. 

But there are problems with EYES, and Mouth, and off course rig, but rig can be easily fixed in CC4. 
But what with eyes, and mouth, and brows? It also need to be fitted to the scanned characters representation of them? 
Can't I use the ones from that scanned character? Or can't it be somehow added in CC4 by something? 
Also how to fix bones placement for eyes, mouth, I assume I should done it in Blender, and then what? Will it somehow snap eyes and mouth meshes in CC4? 

That is really the last things in that whole GREAT pipeline, because I like to use scanned data, with really realistic results. Can someone cast a light on the topic?
 

You would need to reposition/resize the meshes for the eyes, teeth and tongue, in Blender, to match the new head topology.
Then in CC4 when you use Adjust Bones > Auto Position it will match the eye/teeth/tongue bones to their respective meshes.
After that, you can use Modify > Proportion to further tweak the positions of the face bones as the proportion editor moves the meshes with bones.

(Or, you could just jump straight to Modify > Proportion and reposition the face bones there, but it's easier if the meshes are roughly in the right place first)

Use Modify > Fix Eye Element to fix the eye occlusion and tearline meshes.
Finally, eyebrows you can just replace with new ones, and they will conform to the new face.

@Victor, I thought there was an easy way to bring in the textures from 3D scanstore and customize the texture to the CC4 character textures, normals etc to get higher fidelity textures. Can't find the tutorial, there was a great one from last year and I had saved it, but I think it's been removed.

Perhaps you know the easiest way or @Bassline303

Yeah, so it need to be done like that, but nice it anyway is working great, and little hassle with mouth, and eyes, well it's nothing. Thank You for the other tips also :)
