Below are some image examples that seem to cheat the lighting according to me.
I've heard that these tricks can help it :
- flattening the eye with a lattice
- having enough SSS in the eyelids to prevent too much AO on the sclera
- increasing the brightness of the eyes in compositing using the object ID of the eyes
but do they also sometimes mix the eye's realistic shader with a shadeless shader ?
I mean, look at Violet, her screen right eye is partially under her hair, and it looks just as bright as the other eye.
