hi rick,
thanks for replying me. my settings are as follows.....:

Primary :- Irradiance Map
:- high animation with 50 samples

Secondary :- lightcache
:- with 1000 samples and prefiltering is 600
samples size 2
world
interpolation samples 20
glossy rays checkbox is on.

and my light settings are
four directional lights with projection map having shadow map of size 2048.

Two Vray lights
intensity is 15
store with irradiance check box is off
smooth shadows on
subdiv samples are 20

For material settings
i m using falloff reflection for all my book maps
and sample size is 20


Thanks
Yogesh

Can you PLEASE let us know if any objects or lights are animated in your scene. We cannot solve your issues without this specific knowledge.

If they ARE animated, you CAN'T use an IR map without having some issue of flicker. IR maps only really work stills or static scenes. I suggest you look at that link I sent you earlier.

If they ARE NOT animated, we need to have a closer look at some other possible issues. Possibly if you are using interpolated glossies.

A screen shot would have done, hehehehe....
Let's see...
- What's your Hemispheric Subdivisions set to?
- LC sample size is in what? Centimeters? Inches? Remember, you have to set you sample size to a small value in order to get a more accurate solution and get rid of deffects (meaning flickering). Also, maybe your prefiltering settings are too high.
- Shadow Map? Why would you use that? You have VRayShadows, faster and more realistic!
- THis probably has little to nothing to do with the flickering, but why use falloff reflections on the books? Are they really that important?

hi chris thanks again for replying me so fast..
yes my two vray lights are animated with the camera. they are linked with the camera. but my objects are not moving they are static.
if i use universal settings then it takes long time to render. actually i have a deadline by tuesday so if i use the universal settings then my animation won't render within the deadline.
can you please suggest me some good settings for HDTV animations. because i have to render only HDTV Output for all of my animations. and pixel size is 1920 X 1080 .


thanks

hi rick,thanks for replying ...
Shadow Map? Why would you use that? You have VRayShadows, faster and more realistic! :- if i am using shadow map for four directional lights because i am using a animated projection map of the window and leaves.

thanks

You might really want to take a step back and try to make this as simple as possible. You're really shooting for some unusual things. Even if you didn't have a deadline, I would avoid animating lights or any other objects until you are VERY comfortable with the whole process, because it aint as simple as throwing in a few settings and sitting back for the results. And as Chris said, it will bring about some incredibly long render times. If you throw 1920x1080 on top of that, forget about. Why are you rendering it in HD? Is it because the client is asking for it that way...are you doing it as a type of supersampling approach to improve the quality? How are you even going to record and playback the HD animation?

Hi brian ,
I am working with Digitaljuice animations Pvt. Ltd. actually we are a product based company. and all our animations are on HD only. so i have to render on that size only. and our proces is like we are rendering oure animations on 60 fps so that enduser can use it on either 30 fps or 60 fps. and we composite our sequence in AFx with Field render.
please visit this link www.digitaljuice.com


Thanks

Yogesh,
I took a quick look at your settings. First, you're set to a fly-thru animation and you have moving lights. Remember what Chris said: if you have anything other than a camera moving (even an animated shader) you'll have to go brute force. Period. That means you'll need an awfully long time to render everything, and using HD definition you're on to a long, long, loooooooong wait.
Piece of advice: avoid moving things as much as you can. Even the simplest animation will take ages to render with moving stuff, so try to avoid it. But, as your job requires it, I'd say you'll need to change your settings to single frame (as already spotted) and try to use a renderfarm. Believe me, you'll need it.

Three things...

When doing a HD animation, you should always plan on at least an hour a frame for renders. So always plan ahead. That is critical.

Next... you can NOT animate the lights (as everyone else is telling you), at which point you can bake the IR and LC maps

Or you can suck it up and use the Universal settings, as I suggested, with the slightly lower settings of min 1 max or 25 and clr thresh of 0.002

Other than that... you have no other choices.
