After a few days tediously and relentlessly testing in iClone 7, I managed to create a modified CC3+ character as a Cloth to apply physics.

I've also been testing out cloth against cloth and cloth with object interaction (recently had one cloth character punching another  :laugh:. ) I have experience using unity and can point out some obvious issues

Also displacement mapping for SkinGen is possible. I know what iClone/CC3 has and needs to make displacement for SkinGen and softbody in iClone/CC3 possible but I'd need to be, should be part of any beta testing.. I'm a CCD member and have been invested as an Elite Customer several times, I have contributed a lot of personal time and resources to deeply test and solve these problems that others working for Reallusion would normally get paid to do and really I wish I was getting paid for R&D to get some thing in return.

Here is a CC3+ Character I created professionally with displacement mapping.. It took a few years testing here and there to figure out how to get this working with iClone since there were no tutorials and no examples of full characters using it without cracks.   Again I know how to create characters without cracks, know what would be required to add to SkinGen to make it work -most tech already exists but there is a bit more that needs to be added to eliminate cracks. In this project I didn't have to mess around with any multipliers.. but people could on default character to get the skin/wrinkles displaced and actually look bumpy.. but there is a problem.. some of skingen's normal map layering seems to cause artifacts (odd shadows that don't move with lighting angle)This likely because it is just layering and not mathematically adjusting pixels on the right axis to properly mix normals.

This is what I was talking about that users can create displacement instantly with their characters skin but there is a trick..
Using a normal map as a displacement texture  and adjusting the image softness to 1.0 you will get some good displacement!
You have to either manually paint the left and right side of the normal map with clone brush to match the pixels or cheat by mirroring the left to the right or vice versa. Any area connecting material parts need to have similar pixel tone otherwise it tells the verts to go in different direction causing a tear/crack in between UV materials.
  

In order to do things properly in Skingen, users paying for it shouldn't have to make these kinds of corrections and that's where I come in. SkinGen could be made to work to have a global tiling texture as well as assigning it to particular areas. 

Lastly using soft cloth and Displacement mapping compliment each other. They both bring realism/complexity to the character and using cloth, little to no tessellation is required for displacement because cloth subdivision gives cloth extra verts.. in fact if you enabled both, your renders or computer would likely come to a crawl so using them together just decreases performance just a little more rather than overkill.
