SBS the Def Surf Mat thing happens when you have forgotten to give something a material, if I remember rightly you get it when the objects are grouped together. In Hex select the object one at a time and keep an eye on the materials tab, the one you've missed will not show in the materials tab.

This one is for Kim, she gave me the water-lily candles idea. As you can see, it needs a bit more time to clean things up but as the girl has no clothes on I'm sure no-one will notice.
