Im trying to produce a meteor effect using fluid shaded particles. However im coming up with a couple of problems which im hoping someone on here might be able to help with. This is the video

http://www.youtube.com/watch?v=rei4o4YWtgI

firstly, for the first half of the sequence the particles show a lot of jitter from frame to frame but later this problem somehow fixes itself?

secondly, about every 5th frame i seem to get a grey render which also causes a more obvious flicker type effect that looks really bad but i dont know why?

thirdly, at the moment i am using the opacity input bias linked to a userscalar to fade the particles as they age, however this doesnt look right. I want the particles to fade more realistically. What would be the best way to connect to particle sampler to control this?

any help is much appreciated,

thanks

Let me know what you think!

I recently upgraded to Nuke 6.1, but now a script created with Nuke 6, I gives me an error for the UVProject node: "UVProject: Missing ‘N’ Channel from geometry". Does anybody know how to resolve this? Does it have something to do with the obj. files I use to project on?

Thanks in advance!
