Hi all, I'm trying to create a custom body morph slider so that I can adjust different cc3 character bodies to one single shape.
The end goal here is to have one avatar to simulate clothing on in Marvelous designer so that I have to simulate only once, and swap a lot of different characters with the same clothing piece in 3ds max.

I used the method Reallusion describes here:
https://manual.reallusion.com/Character_Creator_3/ENU/3/Content/Character_Creator_3/3/06_Customizing_Morphing_Sliders/Morphing_Default_Character.htm

For testing and to keep all things as uniform and measurable as possible I start with a default female character with exaggerated features to clearly see the defects.

I create an obj and an iAvatar file.

Next I create new default female character and reset all the sliders to zero as described in the manual. I create a body morpher with the iAvatar file and check adjust bones to fit morph.
Then with de default character and all sliders at zero I set my new morph to value 100.

Everything seems to work but when I import the exported obj which should be exactly the same size it doesn't match up.
I import my obj as an accessory, I parent it to the rootbone and then zero out all the values in translation and rotation.

It doesn't seem much but in simulating clothing this difference creates a lot of clipping because of the mismatch. Also in 3ds max the same mismatch happens.
What is going on here? Can somebody please help me?
Thanks, wilbert

Nice tip!

@lianchiu

Thanks for looking into this, sadly the steps you took are the same as I did. So doing exactly the same as you I get a different result. 
I don't know what's going on but I'll try to create a new scene again to rule out human error.
