White Powder Explosion

[daisukem]

Hello. I will be working with fluids for a project, and need some help. Basically I have to create powder explosion like a picture below.

I can't seem to get the spikey motion at start.. does anyone have any tips of how to achieve the effect?

thank you.

I have done something similar with some decent results. First, I created a directional particle object with a resonable spread and animated the emission burst. I then instanced a simple sphere to my particles. I used Nimble Tools' Uninstancer and baked the instanced geometry. (Could also be a rigid simulation, or just keyframed geo). I then used the baked geo as emitters in my fluid volume along with the main emitter.

Hope this helps.
