This is the most crucial part of the process that defines how VEXUVIUS looks on the surface.  I called it the "CLEAN UP" work where every surface (face meshes) needs to be detached >> normalized >> united to produce proper SMOOTH surface by removing the (surface meshes tension) to be pre-rendered to produce the final raw product of VEXUVIUS.  Its more like clay work and then we sharpen the surface to get proper light reflected on the surface for render smooth linear looks or vertex rendering detachement to get actual real look of the SUV minus the paint.   This is PRE step before going into rendering work to produce UV MAP templates.
