Explotion effect using textures and shaders crosses terrain

Hi

I’m looking for solution of doing nice explotions. I found few Explotion Packs and I’m trying to do something with them. But there always is a little visual problem.
When you do explotion on terrain there is always this “texture line effect” where textures ( flames, smokes ) from explotion effect crosses terrain. This doesn’t look very nice.
Because I’m using camera view from top ( I see my character and steering it ) I found a solutions based on little cheating … in fact I’m not doing explotion on terrain but in half way between object on terrain and camera, so I’ve got pure explotion.
But I think that this is only current solution and when I watch videos from gameplays I’m wondering how to do nice explotion without those steps. Something 100% based on particles ?

Any ideas ?

What you need are “Soft Particles” - here’s a reference on that:

Oh, that’s it.
