Hi I'm doing some testing with other applications, Namely Zbrush, Substance painter, 3d coat and Blender. 
All of them use a PBR workflow to some degree. 
I'm trying to figure out how to assign the maps correctly in each.
When I save out a Obj File the following maps are exported
AO (Ambient Occlusion)
Diffuse
Metallic
Normal
Reflection
Roughness
First question is which PBR workflow is Character creator based on ?
Gloss / Color Specular
Gloss / Metalness
Roughness / Metalness
Can the PBR workflow that CC3 uses be changed? or specific maps exported?
Which exported map should be used for displacement? 
Thanks for any info on the subject.
