Hi folks. It's a long time since I made an animation that had this small a
file size... Anyway, I was playing with emission media. The animation shows
a "plasma ball" using a density colour_map (the pattern is spiral1 btw).
Does anyone have any ideas about the weird line artifacts? I presume they're
due to the media sampling parameters (left at default at the moment). Any
ideas what I should change them to? (It looks like I should be using method
3 - the docs aren't too easy to follow here...)
Enjoy!
Andrew.

Only two ways I know of that really affect intermedia artifacts and that
would be samples and intervals. Method 3 is default so I guess you meant you
used the default. Intervals are increased automatically for that method. If
you use two different sample numbers for min and max that could cause
graininess is all I think but perhaps not lines. Might try the jitter
keyword.
Seen your image for this, building up to something good there.
