I realised CONXERTO release date will have long way to go since i've been trying to smoothen the surface via  "NORMAL" process which is a bit sucks doing it on Z-modeler tools.  I do have option using blender but it will took me forever to learn how to retain my brain again.   I know its a hard way to do it but i'm comfortable with that.  I believe i can pull a clean "NORMAL" surface in this week before i decided to UV print for texturing.  I do remind myself to to put to much shadows or "Burns" shaded layer since someone over TM needs a plain ones for conversion and painting ease.  The picture below shows a new fix to CONXERTO rear end.
