In one aspect, a first device includes at least one processor and storage with instructions executable by the processor to receive input from a camera and to identify, based on the input from the camera, a first lighting condition of a scene showing a user. Responsive to the first lighting condition satisfying a first criterion, the instructions are executable to transmit a first video stream showing the user's face as captured by the camera to a second device. Responsive to the first lighting condition not satisfying the first criterion, the instructions are executable to use a model to generate a 3D representation of the user's face according to one or more parameters related to the user and to transmit a second video stream to the second device that shows the 3D representation. The model is also trained under lighting conditions satisfying one or more criteria.
