3hr session speedsculpt in ZBrush we did at the Blizzard. I started with Zspheres, converted it into dynamesh and continued sculpting until I got something that looks cool. Then I did auto retopology with ZRemesher, created temp UVs and polypainting pass. That was all done in 3hr session. After that I've spend additional 1-2 hrs setting up materials, lights and rendered few images in Redshift for 3DS Max.
