Actually, I thougt those artifacts made it look even more authentic, because they are a naturally occuring phenomenon.that's why it's so nosy and some times some white small spots appear on the snow (albeit them looks sometimes OK but actually they are render errors)
I was going to ask how you managed to do that (I would've had to do it in a compositor). Maybe they weren't artifacts after at all. Assuming the snow surface materials had even a small degree of reflectivity, it might have actually been an accurate result. Also, if the snow material has some subtle glitter (like you find in some car paint materials) added, I guess you could get a similar result.
That was one reason why I was pretty upset in the other thread...this level of professionalism rejected in favor of...well, I'm not going to keep beating a dead horse.

Julez4001 I overclocked them by my self, it's pretty simple, just rise the clock host in the bios settings and live the rest to automatic ( i have Gigabyte DSP4 and Asus WiFi mother boards) and disable any power saving settings. Unfortunately i have stepping B processors - they can't be overclocked more then 3.1 Ghz and be stable ( actualy i managed to get 3375 Mz but them half time was freezing and half time didn't won't to boot). The F stepping can run up to 3.6 Ghz, so if u going to bay one ask about stepping. Of course u need some good cooling system - with box fan which come with processor - even don't try ! I have Termalright Ultra-120 eXtreme - the best of the best for today and Cooler Master Hyper TX2 which is bit weaker but really cheep. First machine build for me, second - i build by my self and overclocked them by myself too. I get additional 600 Mhz which is 25% from weir factory speed - and i get exactly 25 % of speed increase in render times !
AbnRanger thank you for your support, and yes Signa 2 which was used to snow, have some small degree of reflection on it , so may be it's accurate result.

Yea but still ugly
So, how it was at Sigg ? Any chance to see your presentation elsewhere ?
It was just a quick interview format Q+A about our use of LW. Newtek had some camera's pointed at us so I imagine they will edit that stuff down eventually.

About 10 minutes, twice a day while the show was running. They managed to get a decent crowd each time. Unfortunately they didn't have permission more media other than some stills...

Played a bit with FiberFX - not bad at all ... The only disappointing thing is that fact that FFX can't be used with regular DOF and photoreal motion blur. This one was rendered with 5 motion blur passes, and it's was quite slow (around 20 min)

Have you tried rendering out to RPF or EXR and using the DOF and 3D Motion Blur post effects in something like Combustion, AE or Fusion, yet? As dark as that scene is, I would try that first. Should save you massive amount of time.

you could try changing your fiber fx settings to volume only (although you'd also need to start more or less from scratch on the other settings to achieve the same effect) but this should give you correct DOF effects without having to crank up the motion blur.
Of course it will almost certainly crash using volume only and you'll hate me for even suggesting it but in theory that's how it should work.

Thanx for suggestions guys, the RPF with DOF definitely do the trick albeit I'm not really like the result - it's looks like glow (but perhaps it's my fault, i'm not composting guy, used AE to get DOF, and i dont have any idea how to achieve 3D MB in AE).
The Volume only looks exactly that i'm looking for (in terms of DOF) but rendering time was 56 min! May be i need to change some settings, just switched it ON. Also i get some strange artifacts (lines) on fur. So meanwhile the solution is post DOF, and it's pain in the *** cause i have huge volume light in scene. Ah, and b.t.w. LW was stable during the volume render, no crashes.

Yeah, you'll have to tweak your DOF in post to get a satisfactory result. You could create a mask around the fur, so that the DOF is only applied to everything outside of it.
I use Combustion, which has 3D Motion blur, it's an intelligent method and uses the Velocity channel in your RPF file to apply the motion blur (based on the normals displayed in the velocity channel).
For After Effects, it has a built in motion blur that is more of a simple frame blend...but you can get inexpensive plugins for the real 3D motion blur
