In Zb you can form meshes like forming clay with your hands, select the tool and brush the form with the wacom, very easy to learn. And you can paint textures direkt on the mesh and expost as texture and displacementmaps for rendering in other 3D programms. In typical 3D Modelling programs Meshes are build with mathematical tools like nurbs and splines, input is more in form of typing in numbers after selecting the polygones you want to form. It is more accurate, but not so easy and creative. Hope this answers your question..;-)) Since i have ZB i will never bye an character again, making custom morphs for Poser is a breeze. So it is worth the money...
