Afterburn: Explosions

We want to adjust the falloff value to 1.31. Basically this will make the edges a lot more defined which is what we want to make the fire more visible. Adjust the step size to about 0.768. That way it'll render fairly quick and still output enough quality. Also make the rendering type an octane shader rather than raymarcher.

Under illumination/shading parameters adjust the ambient colour to have a slight gray value in the middle of the gradient ramp, not much of one, something around 40 Grey value and leave everything else alone. This way it'll give it a bit of illumination just as it begins to turn to smoke.



Now we need to set up the gradients. Basically we want the first half to be red since it'll be the 'alive' half and the second half to be grey or black since it'll be when it fades outside the lit radius. Set up the amount of gradients to be three, and set the gradients up to look like below.

Basically the first half to be firey red and the last half to be grey or black. If you click on the gradients you can download them







Change C1>C2>C3: to density.

Now under the particle shape, animation parameters we need to adjust the radius to be 10 to start off
with and after you enable the AFC ramp make the high value 20.What you'll then need to do is adjust the ramp by
clickin on the AFC controller so that it peaks to it's maximum size a lot quicker like the graph below.
