Please, need help to simulate real skyscraper glass at VRAY

[AcesHigh]

Hi there... I dont know what I can do anymore... Ive been messing with the setup of the glass for hours and cant achieve what can be seen on real world photos...

this is the photo


notice the skyscraper with dark green glass...
1- everything inside is dark
2- the black stuff inside stays BLACK COLORED
3- the white stuff (like the curtains) get a light green color

I simply CANT replicate this at VRAY.
-Things inside the skyscraper stay too bright
- the black things behind the glass get green
- the white things behind the glass stay almost white!!

look how the upper floors without the glass, the black stays black... just like in the real world photo... but in my render, the black areas get quite greenish. Same thing with the white parts... they get much much green in the real world photo, and in my render, they just get a little gray

Re: Please, need help to simulate real skyscraper glass at VRAY

Are you setting the color of the glass with refraction color or fog color? I'd say that I think you need a stronger fog color or multiplier, so that it picks up a stronger green tint. As far as getting the inside much darker, there may be too much light getting in there. If you're using LC, I'd stay away from that and move to DMC which will allow you to limit the number of bounces.

im not using refraction at all actually. The glass panes are single faced because there are thousands of them.

anyway, if I used refraction with fog color (to tint the glass), would it change anything about darker colors behind the glass being seen with the glass color while bright colored areas do not get the glass color?

if it's single faced u could make it more opaque (take a dark grey/almost black colour for transparancy), and also a darker diffuse colour. And use an enviroment map for reflections. I used to have the same problem and for me it worked fine.

. . . also, There doesn't appear to be a ground plane or any surroundings (models, billboards or 'environment') so the glass has nothing to reflect, other than 'sky' so it may appear lighter than it should.

yup david has a point, i would definitly play with fog on the glass, be sure to make the glass double sided, and use components to make sketchup happier, my last big project using fog on thousands of double faced window components:

i feel like shit after seeing this marvellous render...

Feel inspired!

the glass is half full, not half empty.

Aces High,

This is a quick attempt at the green tinted glass in your reference photo, using single face glass, diffuse colour 0,101,80, transparency 166,166,166, no refraction, no fog, fresnel IOR of 1.8.

nice try Jackson...that look very nice

Re: Please, need help to simulate real skyscraper glass at VRAY

Jason, what color of reflection filter you used?

anyway, here is my experience using your settings. Still not what I want (dark areas inside not as black as the ones in the real world photos), but better than I was able to get so far. Thanks

edit: thinking better, it got very different from your result. Much less reflection. And the white curtains behind the glass got much less of the green color than in your example!
