Flickering problem - Noise?

[Anonymous]

I've some problems when I work my some renders on Nuke. The flickering is very remarkable.

I thought the problem was about the specular components and materials, but changing the glossy samples(from 2 to 6), it doesn't work correctly. Same problem.

By the way,the others materials and samples (AA or diffuse) are correctly. And just two lights for the scene.

What could be the problem?

Thanks!!

Hi @Jose Torres, can you post a small clip of the flickering? That will help debug it.

Quick question. Are you using an HDRI to light the scene and if so, have you tried turning it off or using a different one? I have witnessed, on the rare occasion, certain HDR images causing noisy renders.

Hi @Dade Orgeron . No, I´m not using any HDRI. Actually, I´m just using two or three lights. (1-2 area light / 1 spot light)

You can take a look to the render settings (two high for the second test), and just 2 seconds of the animation. But I think you can see the problem. And you can see a test about the Direct Specular (Aovs), but I´m not sure that´s the problema. Anyway,

At the first,the result was very high at that area., so I suppose was the specular, but glossy is 5.

Two lights in this scene,samples 4 both.The point is, all renders have the same problem. Some of them, on specular areas of the materials.

Thanks¡¡¡
