Problem with visualization of environment

Hello,

I have trying to import an HDRI into an environment in my 3D model but it does not appear in the Rendering viewport or in any previsualization (even in full render).

Same occurs with ground plane, when I try to create and apply a water surface.

Could it this be with some parameters in the options tab? Am I doing something wrong?

Thank you in advance!

Hi Francisco -
Please post both a .3dm file that can be used to troubleshoot and the output of the Rhino SystemInfo command.
