Weird Flickering of Material in Animation

[Per-Anders]

ok i can't view those avi's here on my mac, but it sounds like it oculd be a number of reasons. firstly if you're using procedural noise then you should stick with stuff like FBM which wont flicker (the other noises will) if you really need that other noisetype then make sure you lower the octaves as far as you can, that hsould help some. also make sure you use a good anti-aliasing setting, you may need to not just make it "best" but also higher setting. then the third thing iflickering can sometimes be is soft shadows, to get around that you really have to up their resolution which is a pain. then there's radiosity (caustics fors ome reason aren't flickery in cinema, theyr'e very predicatble) anyhoe radiosity can be painful, you have ot make sure your'e saving a single solution and all the rest to get rid of flicker there.

anyhow, hope that one of these covers and helps you with what you need.

I am using Soft Shadows in my lights and I noticed that each light has the Noise - Soft Torbulance on.

I upped the Shadow resolution to 2000 and I am re-rendering and I will post results.

two things, Are you using anti aliasing and if so whats it set at, second what codec are you using?

[marcopio]

The Antialiasing is set to Geometry (because when I set it to Best, the objects where not sharp enought, they looked a little blurry).

I am using the Microsoft MPEG-4 Video Codec V2.

But I can see the Flickering even before I use and Codec.

[LucentDreams]

you need to use best, if the image is not sharp enough use a different AA filter. The reason it flickers is that sharpness though


Sharpness =jaggies, jaggies=flicker.

I am rendering right now with the Best option. I also have the AA Filter to Animation now. Before I had the Animation filter to Still Image.

[marcopio]

Well, I tried the different options, but it looks like the Flickering got worse.... Weird.

Would it help to post the project or texture settings?

Can you afford (time-wise) to use Scene Motion Blur?

I had a strange flickering problem in one of my scenes. I could not figure out what caused it, but I noticed that using 25x scene motion blur got rid of all the flickering.

Since the SMB blurs the result somewhat (compared to just using antialiasing), I also added a 20% sharpen filter in the Render Effects. I was quite happy with the resulting flicker-free and reasonably sharp animation (even though it took almost 2 hours a frame).

Thans for all of the suggestions.

I am very close to the results I was looking for. It looks like that placing the AA Min/Max Levels to 4x4 is getting rid of almost all of the Filickering. I had my Min to 1x1.

I will post results.
