Material Preview display problem

In the material preview window the sphere (or cylinder, or cube) is always facing away from the light source. Also, the plane is never visible when it is selected and I pan it around to face the light source. Any ideas as to what might be causing this? Images attached

Thanks,

Hi Dmoyes2019,

I believe your issue will be solved by making your material Two Sided.

Select your material result node in the graph, then just check the “Two Sided” box below the “Material” category in your Details tab.

Curious to know if that helps, please mark the answer as correct if it does.

Cheers,
