Hi,

I'm using Houdini 17.5.173 and creating a simple comp with an exr file and the fog node based on the z channel and a bg mask. For some reason when I render, I see seemingly random frames with buckets that don't have the fog applied. So it will be 1 or several squares on the rendered output images that don't have the fog in them.

Any ideas?

Thanks,

Adnan

Hi there! Have you looked to see if your fog layers are clipping out on either the X,Y, or Z plane? sometimes the fog can get restricted to one side of the image if layered fog is turned on.

Thanks for the reply Kate.

It does not appear to me that it is clipping on a particular plane. It is more like some render buckets are not rendering the fog on each frame and it is not consistent. So I get several squares (I'm assuming render buckets) where the image is there, except for the fog, but the buckets around it have the fog.
