I agree with what Viv said, above. You have to go thru TONS of random batches to find a few really cool and different flames. You can, however, "hedge your bets" and "stack the deck in your favor" by limiting the variables used in the calculation of the random batch - either as I wrote above or, probably better, as you go thru lots of random flames keep track of what combo's of "variations", ie "linear" or "bent" or others, make the type of flames that interest you the most and then set the Options/Random tab to use only those variations. You'll have a better chance to get flames you like. Another thing I like to do is, after I've tugged the ol' three-siders in a flame with 2 triangles around some, add another triangle. It always adds one with a "Linear" transform and it does some neat things to the flame once you move it just a bit. It does get a bit out of hand, though, and tends to spread the flame out a lot. Or, if there's lots of triangles, start deleting them till you only have 2 or 3 and mess with those. There used to be a variable under the transform tab at the bottom labelled "p". I notice now, in beta15, it is different but there is one called "weight". The "p" factor used to change the probability of a "hit" by the gradient (I think - lol) for the triangle selected and you could experiment with changing the first significant bit of this number to thicken up a flame. I assume the "weight' parameter does the same thing. I don't usually mess with it much because, if the truth be known (and eventually it always is! lol) most of the flames I've ever made have pretty much "drawn themselves" and I'm way to slow and lazy to actually try to really pay attention and figure out exactly what makes a flame do specific things other than I've noticed long, skinny triangles make spiky, skinny flames. Now if I could find some long, skinny pizza slices maybe I could lose a bit of weight and become "long and skinny", too! lol Gotta get back in the gym....sure....definitely will.....absulutely....well.....maybe after just a FEW more random batches, ok?" :>)
