ok, i'm a newbie as you can see, and sorry about my poor english ...
here's the deal :
i'm builting a spaceship , and i wanna render it with Povray
but a spaceship needs big rockets (or whatever the name is ) with big
glowing lights , rigth ?
so ... i had one ideia , i built a rocket , then , i put several ligths
near the exit of it , and blocking the way out , i put in there a ball full
of media , just like this one :
http://img215.exs.cx/img215/2451/h9vy.jpg
but i have a little problem ... when i put this ball in front of a bright
thing , like the rocket, it reacts to the bright part and it looks like it
is not there, or something ... i try to increse the amount of media and
make it stronger ... but its not very good , the ball looks diferent if we
look at diferent angles , because the things beyind it change ...
so , my question is ...
is there a way to make the ball's opacity very big , to appear always the
same thing no matter what the angle or scene ilumination is ????
tanks :)

Hal,
Welcome.
What kind of media are you using for the blue ball? Is it only emitting
media? If so, also add some absorbing media with the opposite colour
(1-ballcolour).

Section 1.3.6 here might be of some help:

i have just started my first media experiments myself, also whit a rocket
engine
for that i used emmitting media thats cone shaped. im not sure what you are
looking for but in my case it looks very good.
