Every time I think I've finally finished a character, I render it and realize how bad it looks, so I have a couple questions. Why do the characters eyes go from looking good in the preview, to an almost dead fish eye look in the render? (also how can I fix that?). Another problem I had was the hair (pictures below), why did the hair go from a gray hair looking hair, to a white ceramic looking hair? Some other problems that you can see in the picture include: the skin has a grainy texture in the render, the shirt material looks all weird, and there are some lines on the arms that I have no idea why they are there. Does anyone know why the render looks so different, and how I can fix it?
