Made in houdini, what does /3/ think? This is the flipbook http://imgur.com/a/TYYpW
I was thinking more like a dark orange and red blending in the carbon black smoke like in the pic.
The two on the left are darker and the buring after the inital explosion(like you got going on), the one on the right is the explosion which is very bright and not much carbon black smoke.
What is blowing up? What kind of explosive reaction is it? What is the environment it is happening in? What is the scale of the explosion? Are there any chemicals involved that would alter the explosion?
Needs more red then. In fact more gradient in general.
Yours basically goes yellow->grey.
Better? And again, how do you up the gradient in houdini?
