what am i doing wrong here,
take a look at these examples:
a scene without window glasses
(notice the sky reflection on the table)
scene with window glasses (table reflection is completly gone)
also
and
My workflow includes setting a hdri either as enviroment, or reflection override in vray, and boosting it to values higher than any other light multipliers in the scene. This way i get strong reflections without making materials like wood or leather over reflective.
But, whats wrong here?
Mislim da u prvoj varijanti nista nije sporno. Refrakcija stakla na prozorima verovatno premesta ugao refleksije stola (mada si mogao i malo da povecas setovanja, refleksija na stolicama, ukoliko je uopste refleksija malo puca 
) Probaj da izracunas GI bez stakala, samo sa skylightom i directom, pa da onda vratis prozore i upalis fill (ako ga uopste ima) 
Daj setovanja pa da vidimo.
For the window glass material, did you try to render with ‘affect alpha’ option checked?
you have to increase the depth of the reflections in each reflective material. I would say you set it to less than 5…
