How can I stop specs of light coming through my object? I am currently creating a pumpkin to sing (don't ask) I have got it singing but I have realized that I have specs of lighting coming on the outside of my pumpkin. I really need to get rid of all these light specs on the outsides as it is not very good. I have tried moving the light around etc. but have not solving the issue.
