FaceRef is a browser-based 3D head reference tool for artists and AI portrait workflows. You orbit a 3D head to set an exact yaw and pitch, move the key light to study portrait shadow design, then export structure-first output โ Loomis construction sketches, Asaro plane studies, and depth or edge maps ready for ControlNet in Stable Diffusion, FLUX, and ComfyUI. The 3D viewport and three low-resolution exports per day are free in the browser; Pro adds 1024px exports and higher daily limits.
