"Damn you Arch Vile!" and here's a demonstration of a successful application of DodgeMaster as part of Gun Kata. =D
Are the flames placed as plane layers? Because I am seeing some weird horizontal artifacts near the bottom left corner.
I was using a plugin for DAZ for creating pardecal effects to create the flames. I had also rendered the image twice with different light settings and did some editing, so maybe that had something to do with what you are seeing.
Also I hadn't even thought about the Viles when I set things up, I just had an idea that I had to get out of my head.
edit-sorry about any misspelled words in the post, but as the time stamp showed it's late.
