Face Gen is an online app (or website) that allows users to create realistic 3D-face models based on photos. It offers a variety of features to customize the face according to the user's preferences. The app uses advanced facial recognition technology to accurately capture the facial features and generate a 3D model with realistic details. It can be used to create realistic 3D avatars for video games, virtual reality, film, and animation. It also offers advanced tools to adjust the textures and facial expressions of the 3D model. Face Gen also allows users to share their 3D models with friends and family.
Blender is not an alternative to Face Gen period. Sure, you *can* create 3D models of heads with it, but it lacks all the automation features that make Face Gen what it *is*.
