Vray flicker free

Mga vray masters. Baka may advise kayo how to get flickerless render from vray with moving objects. not static walkthrough. so far ito ang drawback ng gi rendering.
I made a simple test on my own di ko pa rin matanggal gi flicker especially sa corners. Post ko scene file for those interested to test the scene and to compare render time.

http://rapidshare.com/files/249811308/vrayanimationtest.zip.html

max file with moving objects in a kernel box
vrayhigh - medium prepass, high lightcache no mb. 3:20min per frame.
vraylowmb - high prepass, low lightcache with motion blur. 1:20min per frame
test00- ibang renderer gamit ko. 2min per frame

used my qc6600 for testing.

raytracer sa vray SP1.40 SP3a we're using the prepass+animation method.

if you're familiar with this, ito ung irerender mo muna ung IR maps + light cache maps before rendering the final image. previous vray releases we had to do this manually pero sa new version madali na lang.

here's also a link to the tutorial:

add ko pala in our experience u dont have to use the brute force for 2ndary GI light cache will do.

dude mush, matanong ko lang anu ba ung brute force? I cudn't find it anywhere in vray 1.5, sa lower version lng ba un?

TIA

Send me a copy geo, I'll take a look. Can't download sa rapidshare - limit na yata.

@torvicz

ung brute force nasa secondary bounce option - it used to be the old QMC secondary bounce, which is longer but of course is meant for animation. sa bagong release ung animation (prepass) + animation (rendering) fixes that flicker issue, easier to set up, unlike before na u have to do the settings manually. in this case we tried the LC option and it works just fine.

light cache, quiasi, at photon lang nasa secondary ko dude?
advanced ba gamit mo?

Brute force is quasimontecarlo.
That's fail proof GI but then again - it takes time to render.

kaya pala dude e..hehe
lower ung saken...1.5 rc3 SP2

by the way i looked at the animation tests done by raytracer - by walkthru standards these are acceptable however if you really want super no flickers - QMC is the way to go.

mushroom - tnx for looking at the file:D . I did use that method pero siguro mababa pa pala setting. Sinet ko irr to high with anim prepass with lightcache 1000 single pass. After calculating switched to anim rendering map and lightcache map. I got the tip from Vitamins thread pero qmc gamit nya with anim prepass medyo mabagal so I used lightcache.
Anyway what settings are recommended?
Ung file na upload ko is brute force pala. Weeh.


v_wrangler - anong filesharing pwede dyan?

Here's the file I made to make the videos. ung may gi flicker sa shadows.
http://www.filefactory.com/file/ag964ed/n/vrayanimationtest_zip

Added
zanimation00 max file with irr and lightcache method.
zanimation max file is brute force.

Btw, max 9 with vray rc 5 ung nagawa ko. Try ko sa ofis with max 2009 and vray sp3 and upload it for those with access to vray sp 3.

How to achieve good render times with same quality as test00.mov?

ok nadownload ko na - tingnan ko lang muna.

Tnx vertex. try the new link nandun ung anim prepass/lc method. Disect it, explode it. I'm sure meron talagang way na mawala ung shadow flicker. I just don't know how Baka pag uber high setting mawala na sya

nay mataas tlga settings na kelangan mo raytrace, kung pang broadcast to. sa walkthrus kasi severe ang flickering hehe - so a medium setting with LC as 2ndary bounce ok na. otherwise i dont know any method for shorter render times and 100% flicker free.

ill leave it to sensei vertex - let's see what he says. take it away roy

sir mushroom, im also interested on this, but i cant download the links, pwede po ba sa www.yousendit.com, marami pong salamat.

Here's an updated file for max2009 and vray sp3.

I made a mistake sa compression ng video codec pero viewable via quicktime parin.
matagal pala mag render irr with brute force kahit simple scene. but there's no flicker. sana makahanap tayo ng balance between render time and no flicker.

Ito po updated version max 2009 vray sp3. pati ung quicktime movie tamang codec na rin. Lol!
Acceptable quality na siguro ito for me. Not that bad render time.

ibang host ulit. sana magkaron cgp ng file attachments kahit 2mb.

George, if you want to render this scene in one pass flicker - you have no resort but to use brute force or use animation pre-pass. GI is tricky for animation and if I'll be asked to do this, I'll do this is a number of pass:

1. Box alone (single image) as BG
2. The animated objects and the box as matte

Then composite in AF.

hmmm...nadaanan ko eto sa net sa paghanap ng magandang setting sa curtain.. at wla ko nakita...

btw..baka eto ung solusyon sa problema mo.. di ko na binasa masyado.

Dynamic Animations in mental ray (without the flicker)!

kya lang mental ray ata eto...bka pwede na rin ma-apply sa vray...
