#Help with fog objects
7 messages in this thread
Problem.
Why when I try to make a Fog Object, it renders "invisibly"? I mean, I follow
that little tutorial in the book, and apply color and fog length that is about
1X, 1.5X or 2X the Y length of the object. I even tried adding a texture or
adding self-illumination – with no avail! Then I tried to both scanline it and
trace it – but neither displayed the object! I mean it was like when the
generating pallette came aroung, no pallette was generated (or one was
generated in like a half a second).
What's up with that?
Also, I want to create a planet with an aura behind it like it had an
atmosphere and that light shining from behind it scattered through the
"atmosphere" of the planet. How can I do this? I was trying to do it with fog
but I could not get the fog objects to show up!
Thanks, – Brad
I'm having the same problem with fog objects–I render them and all I get is
a blank screen. Anyone know what the problem is?

Put a ground in the scene dont render in simple black, give it
something to be fog against.

Put a backdrop picture or a plane behind the fog object.
That should do it.

HOw can I get the "aura" I'm looking for?
You know in real dramtic space scenes when one planet comes over the edge of
another and the first planet happens to be a sun? And what happens is that
along the atmosphere of the second planet, the light is scattered. The effect
I can get with fog doesn;t do this. I have tried everything and I can at best
get – well not very good!
– Thanks
Brad,
Try using the ring in the sparkle texture (formerly lens flare). This
takes careful placement and is by no means an easy solution, but can provide
the effect you desire. I used thes trick to create the 'ring' for the 'diamond
ring' effect in the eclipse in the Impulse library here.
You might also try nesting spheres of slightly different radii and
applying successively higher filter values as you move outward. If you make
the sun lightsrc non shadow casting, and place it correctly, the sun will shine
on the underside of some of the spheres and create the look of clouds lit from
below (sorta). To see an easy demo, place the planet and source so the
terminator (border between light and dark) faces the viewpoint, and render in
scanline mode. You'll see a limb on the far side of the planet where the light
shines on the inside of the spheres.

Thanks!
I'll try it!
