Hi EagleKing,

I unfortunately don't know what is causing it... I'm fighting with a similar problem when I mirror a face I'm working on... somehow some extra faces is added... and somehow they drag in the original half of the face causing its getting a bit weird an extra dark in some places...

unfortunately I don't know the solution to the problem... but if nobody answers... I will return when I have figured it out...

hopefully someone knows the answer...

regards

Strarup
