Here are a few more quality male and female (mostly female) 3D scans. These are from a site called Triplegangers that I picked up a while back. Their site is down for remodeling at the moment, so there’s no way to check ahead of time what the models look like and if they will be useful for you. But they’re free, so just take what you want and toss the others.
They’re similar in quality to the 3D Scan models I posted before, just some different models and poses.
Each comes with a ZBrush file, an OBJ, and a texture map
