Hello,

I'm trying to figure out how to apply media to a scene though the media tab
in scene settings. I've pretty much got assigning media to objects down
(media make great flames and jets), but every time I try to associate to a
scene instead of an object, my results are sometimes bizarre. If anyone has
a scene that uses media in the scene settings (moray mdl file), a copy of it
to reverse engineer the process would be helpful.

Thanks

What do you mean by bizarre?

IIRC, you have to turn the density of media right down when you use them 
in a global situation.

Frankly, I usually find it easier to confine media to a big cube or 
sphere rather than prat around with global media...  But that's just me. 
:)

Bye for now,

I'm now using a sphere and I get a really grainy texture to the media. How
can I correct that. The sphere is 10, 10, 10. When I group everything in my
scene together and reduce everything to where my "space" sphere is
equivalent to 1, 1, 1, everything looks cool.

It sounds vaguely like you need to tweak the density of your media.

Unfortunately, that's about all the help I can get, because whenever I 
use media, I know it's going to involve at least 50 test renders with 
parameter tweaking inbetween.

I've set followup-to to moray.win, as that's really where this sort of 
question should be asked (and answered <slaps own wrist>)

Good luck, and a happy midwinter festival of your choice to you :)

Bye for now,
     Jamie.
