"Ah OK, I often modified this value, without knowing was it really does :-) ..."

"At the top of the evolution editor directly to the left of the Randomize button is a numeric entry. It controls the amount of randomization you get when you mutate. Making it smaller will reduce the amount of variation in the mutation process. So…"

"Yes the range of generated picture is big. I tested and tested and never get the same picture as you. I don't understand what you mean by : "dial back the randomization" "

"The other thing you can do is to dial back the randomization at the top of the Evolution Editor. Once you get to something you like and are trying to generate mutated variations off of it. So then the amount of mutation for each evolution editor…"

"Here's the actual MSG preset. Like i said above, there are 2 tricks to getting a successful image with this kind of MSG preset. The first is working your way to a place in the parameter space that you like. Since the range of potential…"

"Thanks, I was just playing with these processors while you post your answer, and I didn't get the same result as you !"

"Here's the MSG preset. So the processor chain for the MSG preset is about as simple as you can get. The IterMapGen6 processor generates a grayscale single image stream output. That is then index mapped with a color gradient (1to3GradMap) to…"
