Here is a great set of process pictures from our friends over at LEGACY 3DFX. From a humble block of foam to a finished sculpture of King Croak (from Brotherwise Games' Boss Monster), they documented the entire fabrication process.
Milling the sculpture using FROGMill and sanding the pieces.
Primed and protective coating applied.
Painting and airbrush work.
The final piece. Looks amazing!
Thanks to LEGACY 3DFX for sharing this!
