Thanks Nathan, but could you expand on your answer a bit.....

Q1: Why do I have for recalc the normals? As I understand it, they are
simply vectors perpendicular to a polygon with an abitrary length that are
used to calculate the angle of the polygon in relation to any light source,
why would scaling the object change the normal vectors?

Q2: If I do have to recalc them, how do I get to the normal data?

Thanks 

- Miles
