Fascinating and quite addictive. Many thanks.
I wish - a whole lot - that I had the same experience as the other reviewer. But not so. My system is windows 8.1 using an AMD FX Eight-core processor, 3.10 GHz... There have been many flames that did not render. They would just stop in mid render. I also could not save all parameters on any set that I tried. I agree with the others, that some wonderful flames were created and could be created but it's no good if I cannot do a save.
