I think the problem with them is that it would be hard to get it to look like it was there, as it would be a different colour to your actual footage IYSWIM

myabe if a dirt explosion had a transparency slider, then u could make it slightly transparent to make the colour match, and also it would look like fine dirt smile - the transparency would show the colour of the bg through, making it look more like the actual ground in the area smile

Well, the problem with those kinds of explosions is that they don't give off light, which makes them hard to key. Flame explosions are easy because they give off light, so you can film them at night, and screen out all the black easily. The only way to get an explosion like this would to get a good 3D program to render it, or to buy a professional plugin (footage) from some site. Or blow up some sand yourself. But explosives that big are hard to obtain. And really, really loud.

But believe me, I really would LOVE a plugin like this!! twisted twisted

You could always go the early style Spielberg way by putting a 2x4 in some dirt and when your actor runs by, step on the 2x4 to throw some dirt in the air. It actually looks pretty convincing if done right!

I could probably get the stuff to film a 'dust explosion', but the real problem here is getting an alpha channel of all the debris. The only way I can think of to do it is in front of a bluescreen, which I presently don't have access to.
