If you baked out the bump and used elliptical filtering, is it still a problem?

Hehe Yup meanwhile the only option untill I learn some texture painting.
Thanks

Have you tried to assign a constant value to the input time connection of the fractal node? It is not visible in the attribute editor but is visible in the connection editor.

I've no idea how to do that and how it is suppose to help me. Please give me more details about it.
Thanks.

I am trying to eliminate any inputs that can cause the fractal node from being an animated node which can possibly cause the effect that you are seeing in your animation.
I tried to recreate the effect last night. I created a simple poly plane, assigned a new lambert to it with a 2D fractal plugged into the bump and color, added one spotlight to the scene and animated the camera over the plane. For the life of me I could not get the pixels to "drift". Can you share the fractal and material settings you are using?

Was it a very high contrast high frequency fractal?

Hi Genny Yes, it is almost just pure black or white. The only way I so far could get any flickering was with FG enabled or with a very reflective material where specular highlights move around.

Yup you can download the exact node Here. Just Import it in Hypershade.
My scene setup is simple with just the 2d fractal applied to a plane in a new scene and a camera animating over it. That's all.
Please if you could test it one more time. It will be very helpful. Thanks

The levelMin and levelMax values are the culprit for the animation flickering. The values are very high so the the fractal is returning a very detailed image. Your problem is in essence the same as using a hi-res image with lots of detail for a relative small amount of screen pixels. You get flickering.

I baked the fractal out to a 8K texture and used it instead of the fractal node. Without applying any filtering on the texture the result was exactly the same. The only way I could get rid of the flickering was to apply filtering at the cost of detail.
Question for the animation gurus here, how does one get rid of the flickering but retain the detail.

Thank you so much for trying this out. I didn't go above 4k while baking the fractal node so I thought there was some problem with the fractal node itself.
