Those images are a selection of some I did for customers. DAZ Studio isn’t what I’d call a 3D program, but I had to learn it anyway as it’s pretty convenient when you have to produce a lot of images in a very short time. Every other object added to the scenes are made with Marvelous, ZBRush, 3D-Coat, 3DS Max and set up in Photoshop.
