Glass Refraction Rhino Material

Im having trouble with Rhino Render, specifically the glass material.

I dont seem to find the settings to reduce the material’s refractive properties, resulting in the picture attached.

Does anyone know how can I solve this? That is clearly not natural…

I cannot tell if your objects have thickness - if they do not, you will not get realistic results, or rather objects will look like they are in a solid mass of the refracting material, rather than behind panes of say, window glass that have a thickness. Use ExtrudeSrf or OffsetSrf > Solid=Yes to make solids from single surfaces.
