Sketchup 2021 + Vray 5 settings for vr spherical panorama degrees

I work with vray 5 and I am trying to set a Panorama view instead of 360° to 180° for example.
In the Vray 5 Asset editor I can’t find the parameter to set the degrees. “override fov” in vr spherical panorama has disappeared. Is there any solution? Thank you
