I have been experiencing a lot of issues when using transformer with Genesis 8 figures and CC4. I have saved screenshots that detail what I am experiencing and I will try to explain the issues as best I can.

It is worth noting that I am not getting these issues using CC3 and the same FBX files. I have some screenshots of what I get in CC3 compared to what I get in CC4

The basic issues are as follows

Base material for eyelashes does not import - 100% of the time
Skin materials import with messed up Normals - 80-90% of the time
Tongue not located correctly - around 40% of the time

I have a series of screenshots that illustrate this

CC3001.png and CC4001.png show a closeup of the head after import. The CC3 import is as expected and in the screenshot for CC4 you will see messed up skin textures, no eyelash base material and an incorrectly placed tongue

CC4002.png-CC4006.png show the issues and how I resolve them. These screenshots are with a stylised figure but I get the same results on more realistic shapes as well.

Eyelashes
I add a coloured image to the eyelash base material and this fixes that issue

Messed up Normals
I make a crude bump map from the base maps for the skin and replace the normal maps with these images. Whilst not ideal this largely fixes the issue but it is time consuming

Misplaced Tongue
I adjust the height and depth of the tongue and get it roughly into the correct position. This is far from ideal as I do not know the correct position for the tongue and I worry that if I want to do any facial animation it will be messed up

I also have issues with the way clothing is conformed on import with CC4
CC3002.png and CC4008.png show a full figure clothed view of the initial import for both packages with no tweaking of anything. CC3 is largely ok with reasonable clothes conforming only requiring some minor tweaking, however CC4 is very bad with very few items fitting well without major work. (This is worse with some clothes and better with others)
I also do not know why CC3 uses the T-Pose when importing but CC4 uses a relaxed idle pose and not either an APose or TPose as you would expect. I export from DAZ with an APose.

Lastly I have an issue that is driving me crazy as I can lose effort and time if I am not careful and don't save regularly. If I hide some clothing and then work on an item of clothing, usually transferring skin weights and/or calculating collisions... when I go back to a hidden item and unhide it nothing shows. This happens most of the time and all I can do to resolve this is to load the entire outfit back from a saved avatar.

CC4007.png shows the final result of tweaking in CC4 with the figure imported from the attached screenshots but I had to abandon the clothes the figure was imported with as I couldn't get these to conform well enough

I really like some of the new features of CC4 and the new UI but with the problems I am currently experiencing it is a complete waste of my time and effort.
