Flicker Free Animation Patulong po mga Masters =(

I was rendering an animation project Using 3Ds Max9, Vray 1.5 renderer... po di parin makuha kuha ang flicker sa gilid ng shadows... Any good suggestions po mga Master?... Tanx po in Advance... May settings po ba kayo na pd marefer sakin?... Despirado talaga akong kunin ang Flicker free animation..hanggang ngayon ayaw parin...huhuhuh

sa experience ko ang isa sa magandang paraan para maiwasan ang flicker ay irender mo ung IR at LC as render to file.. sakin usually ire-render ko sya every 10th frame.... then saka mo sya i-load... anyway abangan natin ang mga suggestion ng mga masters

check mo pala itong thread natin sir, baka may mapulot k ng ibang technik dto...

tanx sa reply Tol =)... give me a day to post yong Specs na ginawa koh... Actually, sinunod ko naman yang Prepass na yan eh...po di parin makuha kuha... ill post yong settings ko Tol, from the prepass settings to the Fnal IR... Tanx uli sa reply Tol... GOdbless!!!

Current Settings used in a scene: (na hanggang ngayon may flicker parin)

Image Sampler: Adaptive QMC
Anti- Aliasing Filtr: Catmull-rom

Indirect Illumination(GI):
Pri Bounce: Irradiance Map
2nd Bounce: LC

Irradiance Map:
Current Preset: High Animation (high na po yan)
Hsph:50
Intr Sample:20
Intr Type: Least Squares
Sample Look-up: Density base(best)

Mode: From File (eto yong prepass ko na una na ni-load ko lng after the pre-pass animation) (alam ko dito nagkakatalo-talo ang flickering eh, po ginawa ko naman, po bat ayaw parin?) (correct me po ng unang setting ng prepass na niload koh) =)

LC: (from file din po) na prepass ko na rin po to.... huhuhu... ayaw yata akong tantanan ng bwisit na flickering na to... makuha ko lng tong flickering na to, masaya na po ako...

OTHER SEttings (no need to disccuss)

This is my Computer Specs:
Intel Core 2 QUAD
Q8400 @2.66Ghz
3GB RAM.

Hope masolve nyo po LONG TIME PROBLEM ko.... tanx alot Po =).....

i think its the AA concern.
catmull rom is a no-no for animation specially for com positing process
it may leave you some unstable frames...
just my personal preferences -

i prefer area for this
. and nga pala
can you tell us your work flow on the compo- process
.. messing w. the aspect ratio can also cause some f-

..try it .po sana makatulong

take time to read this
Rendering a walk-through animation

and some here also:
flicker-vray-animation

This is How i did my compo process(from the start to the end)

1) (prepass calculation for Light Cache)

Image Sampler: Adaptive QMC
Anti- Aliasing Filtr: Catmull-rom

Indirect Illumination(GI): (for LC lang muna)
Pri Bounce: LC
2nd Bounce: LC

Light Cache:
Subdivs:1000
Sample size: 2cm
Scale: World (interior ang current scene ko)
# of passes: 2 (para mas madali)
Check pre-filter :10
Filter: nearest
Intrp sample: 10
MODE: Fly-through

RENDER THE ENTIRE SCENE, then after rendering the entire scene,
SAVE Light Cache to File,
Set MODE to FILE, then look for the save LC then load.

2) (Calculating the Irradiance Map)

Image Sampler: Adaptive QMC(same)
Anti- Aliasing Filtr: Catmull-rom(same)

Indirect Illumination(GI): (for Irradiance naman)
Pri Bounce: Irradiance Map
2nd Bounce: LC

Irradiance Map:
Current Preset: High Animation
HSph subd: 50
Interp Samples: 20
Interp Type: Least Squares
Sample look-up: Density Based
MODE: Multi-frame Incremental

I set it to render in every 10th frame
RENDER THE ENTIRE SEQUENCE/SCENE, then after rendering the entire scene/sequence,
SAVE Irradiance Map to File,
Set MODE to FILE, then look for the save IRR map then load.

LASTLY, RENDERING the FINAL ANIMATION:
ADAPTIVE Subd:
Min:0
Max:3
Check Normals (sabi daw to avoid flickering, eh nacheck ko narin po eh)

SET RENDERING in EVERY Nth FRAME
RENDER the FINAL ANIMATION....... and i still got flickered output =(

Hope po Clear sa inyo yong pagkakasunod ko ng Work flow ng compo process ko MASTERs. Kong may napuna po kayong MALI sa ginawa ko, sawatahin nyo na po kaagad para malaman ko mali ko MASTERs...Tnx po ulit sa Tulong nyo... =)
Nasubmit ko na po ang OUTPUT ko sa Cliente ko, po Me as an Artist very dissapointing sa mga Flicker na nakikita ko. Parang naduduling ako sa mga object na makita ko specially pag malapitan na sila sa Camera, parang obvious ang Flickering ng every Frame.... HOPE this discussion would benifit also other CG Artist... tanx po ulit=)

RENDER MASTER yan din honestly binasa ko. po bat hindi ko parin masawata yong mga ****** na Flicker?.... =(

ok. give me till tonite... iw ill make some samples and settings.

ot: i edited your post, bad words deleted

Ay May Mali po pala sa PORTION ng LIGHT CACHE work flow na napost ko....

during the Actual Work Flow, in the LIGHT CACHE pre-pass rendering, nilagay ko sa previous post na "i did RENDER the ENTIRE scene", po sa Actual, i Only RENDER the single FRAME using a FLY-THROUGH MODE then save it in a disk and then load it.... is this the Problem? Should i RENDER talaga yong ENTIRE SEQUENCE when CALCULATING the LIGHT CACHE FLY-THROUGH mode?...or RENDERING a SINGLE FRAME will do? then SAVE it?... baka eto nga Problema ko? TAnx alot po RENDER MASTER. pacenxa na po sa bad words.. hehe...

Kailangan mo irender ang entire sequence kahit every 10th frame or less kasi nagbabago ang distrubution ng ilaw sa buong animation at ngiiba ang areas ng may GI sa isang frame.

ito naman ang lternative settings you can try.
1. Adaptive DMC
2. AA - Mitchel-Netravali
3. Adaptive DMC min = 2
4. Adaptive DMC max = 6
5. Medium Settings
6. HSph Subdivs = 80 (ito yung ngpapaganda at nagtatanggal ng blotches)
7. 2000 lightcache
8. lightcache subdivs = 0.001

rest is the same sayo. good luck!

Hello po Master BOkkins

Adaptive QMC po ba ibig mong sabihin?.. wala po akong DMC na nakita eh...hehe...

try ko po setting na binigay nyo. So i still need to come up a LC pre-pass calculation for the Entire setting po?...like yong ginawa ko sa taas?...den save it uli and load...

Tanong ko lng po Master Bokkins kong kailangan ba talagang i-calculate lahat ng frames sa LIGHT CACHE PRE-PASS?..or isang frame lng ok na para sa buong sequence?

pare di ako master pero dagdag mo na rin to dun sa Light Cache mo, baka sakaling makatulong.

Scale: World..........instead of Screen.

for example 3000 frames ka, kailangan mo icalcute at least 300 frames (every 10 frames) kahit at smaller resolution.

dont call me master bokkins pala. bokkins or bro nalang.

Ok po Lobsang, try ko din po yan baka makatulong... den ill post my reply soon as i finish an output... tanx po ulit

yup sir sa fly through mode , kahit isang frame lang ang i-render sa light cache para sa buong scene..

and then sa irradiance map tama po sabi nila,, kahit every 10th frame...

Ok Bokks, hehe
as of now, im doing the settings na binigay moh.

Pre-pass calculation of LC:
Primary Bounce: LC
2nd bounce: LC

LC:
Subdiv: 900
Sample Size: .002
Scale: Screen (sabi daw ni Lobsang sa taas)
MODE: Fly-though

RENDER scene in every frame (mabilis lng pala ang next succeding frames ng Fly-though kaya't ginawa kong every frame na)
then i save the LC sa disk, then load it again...

NOW the Irradiance Map setting na...

Primary Bounce: IRR Map
2nd bounce: LC

Current Preset: Medium Animation (yong binigay moh)
Hsph Subd: 80
Interp Samples: 20
MODE: Multiframe- incremental

RENDER SCENE in every 10th Frame (as of now niluluto ko pa po, hehehehe)

Ok Tol, as of now niluluto ko pa ang Pre-pass ng IRR Map in every 10th frame... Tanx Tol

Pare...

Scale : World

Screen yung default eh....subukan mong i-world.

Now my output: after 4hours

Pre-pass calculation of LC:
Primary Bounce: LC
2nd bounce: LC

LC:
Subdiv: 2000
Sample Size: .002
Scale: Screen (sabi daw ni Lobsang sa taas)
MODE: Fly-though

RENDER scene in every frame (mabilis lng pala ang next succeding frames ng Fly-though kaya't ginawa kong every frame na)
then i save the LC sa disk, then load it again...

NOW the Irradiance Map setting na...

Primary Bounce: IRR Map
2nd bounce: LC

Current Preset: High Animation
Hsph Subd: 80
Interp Samples: 20
MODE: Multiframe- incremental
RENDER SCENE in every 10th Frame
Save IRR Map to disk, load again.

RENDER ENTIRE SCENE


AT yong result ko is may flicker parin po... pakicheck nga po ng Settings koh na na-Qoute ko po....
Bakit po kaya?

ok po Lobsang, itry ko ulit yong World scale Tanx alot po

DI rin ako master but what seems to be wrong is that you are LC'ing both the Primary and the Secondary. Use IR for first and LC on second, if you are on LC for secondaries, just set it to Flythrough and it will create a single LC pass for the entrire sequence. Of course you should be on incremental add.

Second Wrong procedure. Do not use sharpening filters like Mitnet or Catmull. No matter what you do - you will get flickers from aliasing (not GI) because these filters tend to sharpen the images. Good for stills bad for animation. What it does, is squeeze in so much details perpixel and if it is animated, the sudden change in colors make's it difficult for the filtering algorythm to alias nagsisiksikang kulay beyond the size of a pixel. This is the culprit for scantillation moire and flickerings.

V-wrangler tanx po sa pagpost, pd mo po bang gawan ng work flow yong suggestion nyo?...
Yong first paragrap nyo po medyo di ko nagets, pacenxa po.
can i ask for a work flow of your suggestion? tanx po alot... hoping for your reply

Bokkins ilonggo kaman gali?...hehehehe
But nice to meet you here Bokkins... tani mabuligan mo guid ko sa ginaproblema ko sbng... ang flicker lng guid ah.. amo lng guid na.. may ara ka work flow nga pd ko masunod?... kay gaugtas na guid ko sang flicker...hehehe.... Salamat guid Bokks... hehehehe
