I am a user of FumeFX and have been experimenting on PhoenixFD for a week. I’m quite blown away with the results. Phoenix FD is definitely faster, and gives good looking results with changing lesser no of settings. Plus it has an inbuilt randomize option so that we dont have to draw noise curves in the channels to make the fuel/smoke emission non-uniform. Phoenix takes much of its interface from Fume and many settings are similar.
One problem I’ve been having is that Max crashes whenever I render PFD with Default scanline, and I’ve to do it in VRay always. Maybe its because both are from Chaos group.
I’m still trying it out to see whether it can do all of my work that I did in Fume, will be posting some of my renders soon.
