Is it possible to sculpt a character like this without motion capture?

You mean photogrammetry (generating a mesh from many photos) or face scanning (using 3d scanners), right? Mocap is for animation.
There was a guy on this very board making a similar sculpt of an asian female. Check >>970317 on the archives. It is possible but it requires quite a lot of skill.

All known archives sites are down though

Wut? Warosu and archived have /3/. Most 4chan archives have links to other archives with board lists. Like for example go to the 4plebs "credits" page, it has a list.

It's possible to sculpt anything man

>>1007936 (OP)
Yes, I made a similar woman for a project without a 3d scan recently, it's going to be difficult for you if you're new at sculpting likeness.

>>1007936 (OP)
not for you it isn't

What about a train? Could one sculpt a locomotive?

>>1007953
No, everything except trains, they are impossible

>>1007949
Just wait for 3d ai generators

>>1007953
Literally anything, however, sculpting that would be unwise

>motion capture
motion capture is for animation not modeling you twat

Technically yes. It's a steep learning curve though. Maybe you could download a pre-made face model and then try to modify the features to get the face you want?

yes, Chris jones did it. look up on youtube. everything by hand in blender and krita
