Vray rendering white after prepass

When I perform a render or production render the render starts out fine. After the ‘6 out of 6 prepass’ it renders the entire image white. Why is it doing this?

If you are using render settings made by other try to make your settings as default,then check v-ray options- camera and other options.

Reset of the global options is a good idea.

I suppose the effect is caused by the setup of the options “show direct light” (IM) and “store direct light”(LC) and a to high light intensity.
