Cycles problem - background not rendered properly

Hi,

I have bumped into following issue: Environment Texture background only renders correctly in viewport. In F12 render, it only provides the light emission, but is not visible and doesn’t provide reflections. It looks like some “ray visibilty” settings issue, but it is not possible to set these for background, is it?
I have read some posts about different render outputs in viewport vs. F12, but they were only talking about normals and geometry, not background.
I have tried different recent MacOSX builds with same behavior in all of them.

Any help would help :slight_smile:

Thanks, Petr
