Ok, I really hope someone can see what I am missing here, but I am rendering my Bugatti Veyron, and all four rear light clusters use the same material set, indeed I have deleted the two right hand clusters in modeller, and mirrored the left ones back over to ensure they are the same.
The problem as you can see is that one cluster is rendering different to the other three. Can anyone PLEASE help as to why? It is absolutely doin my nut in.
Cheers!
