I had some difficulties at the cigar ember, but at last I managed to make it to look almoust real.I said almost because I think there has to be a solution to make it more realistic.
Here I post the hipershade for cigar ember to show you my solution...if you have an other solution, better than mine, please show it to me (cenusa from hipershade means ember, I thought to specify to avoid confusions) I'm waiting any tipe of comments and critics.
