I need to see the buildings on the other side, way more than I see the HDR landscape. Pretty much as it shows in the screenshot below.

Actual render (Eevee). As you can see this is too much

Thank you in advance guys!
There are 2 factors affecting the optics of windows, the light coming from indoors and the light coming from out doors.
Make your indoors source weaker and your outdoors light source stronger.
Nothing like truly understanding the issue at hand eh?
Thank you so much Felix

Update
As it can be seen in this render, even with a Sun light at 30 the HDR image shows too much.
This nodes setup supposedly use the HDR file for lighting the scene while allowing me to choose a solid color. But I’m not sure it’s working.
Is there a way to continue to use the HDR file for lighting the scene while a “different” image shows for reflections only? (I’m thinking city buildings would suit this better)
