arcady,
I'm afraid I don't understand what your problem is. The picture examples you show don't show anything which can't be produced in Carrara, albeit by slightly different means. If it is that important to you that you produce the effect you are after in a particular way (as opposed to the perfectly reasonable method I describe) I'm surprised you didn't check out the demo version before purchasing. The shading system of an app is particular to its rendering methods and there's never a direct translation with other apps.
