Hi, I have been playing with this model which I created in the spline editor. When I apply a smoke glass shader to the part and render it, there appears to be a slot in the model around the candle. See circled area. using a solid shader this does not appear. Is there a way to have the top glass ring not to be so transparent or should I have created this part another way?? rendered with transparency and light through transparency active. Nicholas86 candle shader works well. I am not really happy with the flame yet, too bright. Created in Carrara 4 Pro Any helpful tips would be appreciated. Cheers Neil
