Noise with billboard trees and new Autodesk Proceedural gravel

[creasia]

Hi guys,

 

When I render my images as stills I have no problems. However when I render my animation I get noise and flickering all over the place on my billboard trees and also on my Autodesk Proceedural Rocks material. I am reusing a single FG map only and have 100 samples along my camera path to calculate the map. I wish I had the option of using Vray.

 

I have increased the antialiasing settings but still have the same problems. Has anyone else been able to fix this?

 

I see that there is a grain reduction filter in Composite, and I think that I will try it considering it took 3 days to render my animation.

Here's a good tutorial on animating using MR. I'm linking to his tut on moving camera, moving objects but he has another one which describes moving camera alone.

 

Is you scene an interior or exterior? If Interior, enabling GI + final gather might help because GI is not view dependent.

 

Proceedurals can sometimes be a problem with an animation because they can be calculated slightly differently from frame to frame.

 

How long is your animation (in frames)? You could have an issue where 100 samples is too many or too few.
