Glass Reflection Settings

I’m new to Vray and I’m attempting to figure out glass reflections for exterior window glass. Vray 6 and Sketchup Pro 2022.

I’m trying to determine how to ghost the site reflection onto this model’s window surfaces so that the interior can show too. The completely obscuring reflection that I’m getting currently starts at a more obtuse reflection angle, so one window sash is see-through and next one further away is not. Both of the windows to the left have the same glass - they are both the same components.

I can see that people are creating graduated reflections determined by reflection angles, and Justin Geis’s YouTube videos seem to make adjusting the amount of reflection simply a matter of changing the Reflection Color and it looks pretty simple, but I have tried all of the settings he uses to adjust reflections and none seem to have an effect on the sky reflection. Does anyone know of a more basic tutorial out there? I’ve watched a bunch of videos over the last month, and I know I’ve seen glass reflections covered elsewhere, but I’ve failed to understand reflections and window transparency - I just need a step-by-step in-depth coverage tutorial.

Try add some thickness to your glass object

Can you elaborate on what you mean by thickness? The glass is an solid box 1/8" deep.

if you glass object is a plane now, try give it some thickness

Thanks for the suggestion - that was one the first things I did. The windows in the model had two separate glass layers and would not let any light through, so I made one object with a thickness of 1/8". That is their thickness in when the above rendering image was done.
