Finally, the model is finished. More or less 1250 vertices. Even if the
standard smooth of BLENDER is good, some sharp angles, remain (image 1).
Here, the magic of
Sub Surf will actuate. Set "Subdiv:" to 2 and press the blue "Sub
Surf" button in the Edit buttons window .
WOW!! The general shape ( image 2), and details remains the same but no
more sharp angles. Very strong.
Give the model some clothes and it's ready to show ( image 3).
When using the Sub Surf, BLENDER apply it to an object copy, this way you
can reuse the old one and made some changes if necessary.
