Problem with render and lights
 

i am getting an odd result when I render the following head.

The top pic is what it is what it should be like but the bottom two show what I am getting.

The dents in the mask do not show up and I get these odd yellow highlights and colourings for no reason.

Please help!


Also I am looking for advise on how to set up a descent lighting system for the character.

Any suggestions will be greatly appreciated.

Sorry for two posts.

Please ignore the other.

from this perpsctive i cannot tell what im supposed to be seeing. can you post a more accurate picture please?
