I'm experimenting with the Pyro FX explosion tool in order to achieve an explosion that expands rapidly towards the camera on the Z axis.

I've tried using the wind field as well as buoyancy direction both in Z to try and control the direct the fire is expanding, but I'm sure there must be an easier way to do this? I want the fire to swirl and roll and generally be more streaky than what I have at the moment, which is one big blob. Something like the last clip of this video:

Lastly, I'm having a problem where the temperature gets too hot to the point where the fire is just one huge white blob with no noise or breakup, I've tried lowering the temperature output and the gas released, but it doesn't really help.

If anyone could have a look and point me in the right direction, that'd be great.

You can Key the param of shader to add noise when the fire is all whiter .I think this will work .
