messign aorund wiht making Fog in vue, and also, smoke

#1 this fog made by WAY upping the amount of fog in amtosphere settings to 300% and higher
For real "fog" you have to shove it way up and render at high quality in the atmosphere settings or it's TERRIBLY "noisy".

And now, the old classic, applying a material, in this case, a derivative of a metacloud material which is changed into a basic volumetric material

note you need ot do work so the edge of the sphere doens't show, such as using a huge sphere, or metablob and baking to polygons of a large number of spheres or rocks

And here using a metacloud, each sphere dropped to gorund, made same size, material tweaked for scale of the scene

IMHO, metalcouds make great smoke and non-standard fog :) But render times SUCK if you do not turn off INTERNAL SHADOWS and CAST SHADOWS in the material settings of the cloud material
even then it usually has hellish render times depdning on useage and scene.

Here in northen Italy we sometimes have foggy scenes which would render quite fast in any program: anything beyond a few meters is just a solid white wall :lol:

I have sometimes seen in the evening situations in which the fog layers were just a few meters high, which a really sharp upper border. I think that in this case a simple cube, appropriately stretched with a cloud material would perfectly do.

Visiting the Terragen Planetside forum, I have seen references to photographs of meterological conditions so visually "unnatural" that, if rendered in any app, would make people say "...your clouds just suck... go back to learn the basics".

Bye!!!

How does applying a fog or cloud material to a primitive work out?  It should be less overhead than a metacloud and you shouldn't end up with symetrical edges if you use a course bump map.

The 2nd image is fog material (variant of a metacloud mat, that changed ot a standard volumetric), on a very large sphere :)

and they don't have "bump maps" as they are volumetric, density etc. instead.

Maybe I didn't explain myself clearly enough.  Here are two pictures of the results gained in about a minute (not including render time) by creating a cube primitive, elongating it, flattening it to the hight of the trees and then applying the thin white smoke material that comes with Vue.  I then increased density and quality until I was happy witht he effect.

Here's a more overhead view.  There are no hard edges and a bump map can be applied since it's an object not a cloud.
