Finally this is the moments i was looking forward to see.  After finish the task detaching, normalizing the face meshes and smoothing the spline surface VEXUVIUS true appearance finally revealed for the first time but without texture map yet in Z-modeler.  With normal ambient lighting and simple render we can see the actual contour, shape  and lines on VEXUVIUS.  I'm quite happy to see my design really landed on the right path, the new SUV design was very much sporty, exotic and both modern and robust than i ever predicted.  Tomorrow next step is to double check the minor spline arrangement via wireframe and apply simple gradient UV map to specific part to generate screenshot templates for actual texture works.
