I just have to ask: to get your flames looking so solid, do you concentrate mainly on the weights of the transforms, or the coloring? I only ask because I manipulate the coloring as well as the weights in my flames. I find that certain gradients actually improve the solidity of a flame in spots where weight-manipulation couldn't quite fix the problem.
Thanks in advance, and this flame looks killer by the way.
i would say that weights are more important than colouring in my fractals. The full 'solid' look is from all areas of the image having approximately equal amounts of points transformed there there, and nothing overlapping. Correctly setting the weights will get this to happen - if you have set up the transforms correctly as well.
