Jitter problem

[rakeshtagotra]

i have made a villa . the problem is when i render the frames for movie the jitter is coming on the walls while playing the animation. but if u look at one single shot its looks very good. can somebody help me to avoid that jitter problem.

[kippu]

very hard to visualize what you are trying to say without any images

[rakeshtagotra]

i also can't upload the video to show you where jitter is coming. but i am uploading one shot of that villa.

Looks like irraidance map problem,

Describe the settings

are you pre-caching?

Loading the Irradiance map properly?

[STRAT]

if you dont help us we cant help you

[rakeshtagotra]

what help you are talking about ????

[STRAT]

we cant analise what the jitter is unless we see it in the animation, and if you're not going to post it we cant see it, and your description isn't good enough as there could be numerous jitter causes.

[rakeshtagotra]

Actually start the file size is around 750 mb. that is y i am unable to post it online. by jitter i mean there is some kind of noise in the walls are coming while the animation.

[rakeshtagotra]

ok u do one thing give me ur mail id i will send u some targa images which u can see in ram player.

[STRAT]

not a good enough description. you havent even mentioned what type of gi you use for example.

 

i suggest you take out a small example of your animation to show us, and learn about compression.

[ravi_chawda1981]

Describe wht kind of prmry and scndry engine you are using, including all setting so we can further go on and upload jpeg , if you r interested to share your problem with us!!!

[rakeshtagotra]

i am using daylight with these settings. check it out.

[STRAT]

in vray for c4d you cant animate with single frame mode IR. you need to pre-cache the solution and interpolate it. i suspect it's the same for max.

[rakeshtagotra]

Then plz also tell me how to do it in max....

[STRAT]

try reading the manual

 

if it's a plain camera animation read here - http://www.spot3d.com/vray/help/150SP1/tutorials_imap2.htm

for an object animation read here - http://www.spot3d.com/vray/help/150SP1/tutorials_anim.htm

[ravi_chawda1981]

Ok

>>>do one thing, select the multiframe mode in irradiance map, click all the blanks below and save irradiance map through Browse button(Assign Path).

>>>click the 'dont render the final image' blank in global swithes.

>>>then come to common parameters give the range of your animation and mentioned the interval of frames in 'every nth frame category'.

tht will solve your problem.

[rakeshtagotra]

Thanks Strat. Can i have ur mail id....

[STRAT]

my emial address? sure - sjleworthy@yahoo.co.uk

 

but i'm not a max user. i use c4d.

[rakeshtagotra]

okay no props. its okay. i will add u in yahoo account. keep in touch. Thanks....

[rakeshtagotra]

But strat i am still facing some problems. as i putting the same value in my scene. my software crashed.

[STRAT]

i dont know how to answer you. you need to follow a tutorial, and give us more information about how and what exactly you're doing.

[kippu]

its crashing because you dont understand the settings...and those irrmap settings are the most weirdest i have ever seen... some are high , some are low ...i mean why do you adaptive amount as 0.708? the default works.. and global multiplier at 4.5 ? are you having that much noise that you are upping samples to smooth it ...

 

but if you need help on jitter . i suggest you use LC for your secondary bounce and work it from there...

and dont use detail enhancement for animations too

[STRAT]

i suggest you start at basics with the basic vray render tutorials. digest and understand them first for stills before you try animations.
