Thanks for the feedback.

I'm still having trouble in making conforming clothing for V4, I wish I can make some clothing for my V4 morph.  At one point, I would rather downgrade to V3 or A3.  Then I found Antonia, it is amazing!  In fact, it is less complicated than V4, but the hardest part is the JCM.

Few year ago, I saw a tutorial about how to use bones in Blender to mimic the muscle movement.  I wonder if it is possible in Poser or DAZ Studio.  The reason I asked because I think it is easier than making JCM and the others can use the rig on the conforming clothing.

Otherwise, I think with limited time I can spend on 3D, it will take months for it to complete.
