This head is designed to study the light falling on a person’s head. In the file that you are jumping, the light is already installed The light is made in such a way as to simultaneously illuminate the model from two sides (a dimmer light source is designed to simulate reflexes) Two circular manipulators are responsible for turning the light and turning the camera. Thus, you do not have to set the light manually for a long time. The model is in .blend format You can also download the model in stl and obj formats
