PLEASE NOTE
I have found a bug in the material edtior with this stuff.
When you add the color map and blender tied to the fuzzinessnode, the material somehow gets screwed up, when you reload the scene or material, it's invisible!

you have to delete the blender and color node in the material editor that are linked ot the fuzziness, and add them again. Grr!!!!
Sent ticket into suppport.

Not vital, maybe try using image....it's function to limit the opacity of the nebula, so not vital.

The technique uses a symmetrical standard terrain. Allows multiple colors (shaded volumetrics scan have multiple colours). and nice look :)

Here's one with 2 lights inside the terrain object, with lens flares.
pretty damned good IMHO! :)

The nebula looks awesome silverblade!
Do you reckon you could replicate the Orion nebula, that'd be cool.

I started experimenting this evening.  I have Vue6 esprit, with the latest beta update.  I know that I don't have access to many of the functions shown in your tutorial, but I cannot get a symmetrical terrain to show up at all with a volumetric material, even with density turned all the way up, and fuzziness turned all the way down.

I tried something similar with a sphere, and had some luck, but not much.  I cannot get much intensity to show up, and unless I flatten the sphere relative to the camera, I get a "light blue" effect all around.

Well, I went back in, and played some more.  Instead of using fuzziness at all, I tried playing with the distance field, and got the attached results.

Well, I went back into Vue, and found the distance field option.  Playing with that gave me the attached resulfs.

Stormchaser,
cheers, mate! :)
Oh I'll leave tricker stuff to smarter folk :p

Redtrek,
ah, maybe you've hit something..."Field Depth" defiantely seems to help this problem! great find, sir!
Field depth does seem to increase render times?

that galaxy, oooooooooooh!!! applause!

Interesting effect; looks like a supernova - great work there!

Here's one using a cube filling the field of view.
