Animation with GI that doesn't flicker

[jacksc02]

looks good Vlado, but I think there is a slight flicker on the ceiling

[vlado]

Yep... much less than before though. And the light cache has only 200 subdivs, so that contributes to this.

Vlado,

please could you take a look at the link, no matter what we do, we cant stop the flickering, this was rendered with animation prepass with irr map on high and Brute force. as you can see there is a lot of movement in the irr map, we have lights changing colour and moving, a chair is moving and we have a folding wall.. all these elements we need to render in most of our walkthroughs and is causing us a real headache, it seems to be the changing of colour in the lights that is causing most of the problem .. but take a look...

p.s .. SP3 ..

It doesn't look too bad, but it would be best to get me a scene for this so that I can get a closer look.

Best regards,

Vlado I've sent a few emails over the past week to you but I don't know if they're getting through or not - are they? They'll be from George Rolfe

Files on there way

No its not that bad, but when we have to do a 3 min walthrough and all this stuff is happening in the scene the irr needs to look stable .. from a clients point of view ..

I think it´s hard to decide in this WMV what is GI-problem and what codec-problem - I think the whole banding is a codec-problem, isn´t it? The GI looks stable to me... Can you provide it as Quicktime in lossless PNG like vlado does?

[natty]

There is no difference if i save wmv or quicktime.. the movment is in the irr ... not file compression.

[natty]

But here is the Quicktime version ... www.rendertime.co.uk/vray/test0000.mov

I think it would help a lot if you use a mapped VRayLight for the screen, instead of a VRayLightMtl material...

Yes we are re-rendering the frames now to see the difference..

There is flickering on the wall with the window opening (no, it's not the grain).

There is no flickering, believe me. Here a nearly uncompressed version without grain (QT Photo-Jpeg). It´s quite big, about 20 MB, you have to be a little patient, because we only have 75 KB upload.

But it seems that SP3 does solve the problem. Good news.

Here is another one with a slight camera move also;

This sounds really good. It would solve the problems I noticed while trying the 2-pass-GI-animation-mode.

Vlado, if you are interested I could provide your scene with camera-movement rendered with finalRender - just to see the difference?

By the way - aren´t you in Wiesbaden, Germany, tomorrow - to ThirdDimension? Then I´ll see you there.

tryed this now and to be honest we still have a lot of movement in the irr map..

[vlado]

I'm still rendering mine... on one machine takes a while
