I have been meaning to do a Leonard Nimoy Spock sculpt for a while now. So with the 50th anniversary of Star Trek I decided to get one started and as close to finish as I can.
I sculpted and painted the Spock model in 123D Sculpt+ making changes all the time. Painting the face helped to refine the shape of the head and to paint details that were not possible to sculpt in.
As there is a polygon limit in 123D Sculpt+ and it takes a bit of fiddling to get hard surface details I also used 123D Design for the rank pin and Starfleet insignia.
I wanted to create as much of model as I could on the iPad before I used Zbrush to piece the model parts together and to generate a clean polygon mesh and a tidy UV map which I could create new texture layers in an art app for the Sketchfab model editor.
In ArtStudio on the iPad I created new texture channel maps which included a bump, roughness and new colour/diffuse textures. Then it was all uploaded to the Sketchfab model editor on the iPad at first and then on finished on a PC to adjust the lighting.
