Some good words :)

This tutorial has been written, in order to give an alternative for all of LW users that cannot afford a render farm of Crays in order to render their Volumetric Explosions using Hypervoxels.
So, this technique is about 5 to 10 times faster than Hypervoxels.
I have also made it to have explosions that can be rendered in front of any kind of backgrounds, and not only black or very dark ones.

Some bad words :(

Sometimes, it's possible to see some polygon edges when flying into the explosion. This can be fixed by modifying a bit the path of the camera or by moving/rotating the bad sphere.
If you set a too big amplitude for displacement maps, you'll see polygon edges, so be careful with this.
