Glass problem

I have a problem with Glass in Vray. I’m using regular Vray glass material, and when I have more than two glass objects one behind the other, the glass becomes green. I have tried increasing the depth for both reflection and/or refraction with no success.
Any help is much appreciated.

Are you using dispersion?

Not for simple windows. Try to increase reflection max depth.

An other glass workflow could be - for simple flat architecture glass you could use a material with a reflection layer only. So, you could work with reflection/refraction depth 1 (faster render times). For a solid glass look of visible glass edges you could use a “full” glass material, but only for the edge surface (extract the large flat surfaces before).
