I haven't used my 3d program in 3 years, I'm trying to broaden my experience and knowledge with Photoshop for now so all of those images were done with Photoshop.

The 3d program does not work miracles for you, but it allows you to create a "skeleton" of your furniture, clothing or whatever else which you can apply 2d textures on. With this skeleton, it is rendered in 3d which means you can view it on all angles.

For an outfit, you would have to recreate a human body skeleton that allows the arms and legs to move. Thus, to get the animation you want you would manipulate the skeleton to walk or do whatever animation you want.

It is really hard work, as you can imagine the 3d software is even more difficult to master than the 2d.
