Motion blur problems. Everything lose color when turned on.

I use the usual material with self-luminous. When you turn on the checkbox in the camera, the blur is turned on, but the color completely disappears. Including in the render node from time to time the houdini crashes completely from the error. The color is not lost from the intensity of light with different exposure, all the same problems.

Is it possible to take a look at the scene file?

Sorry, but the forum does not provide this option "You are not allowed to upload files with the hiplc extension."
The problem was solved by changing "Geometry Samples" from 2 to any other higher value.
At a value of 2, the picture is the same black and white.

I think .zip is allowed. You could also send it by email in my signature.
