Real looking glass (yes, again)

[Lupaz]

hehe Io non sono Italiano Though. Just my name.
Indeed, you were very helpful. thanks again.

Let's say you have the perfect glass shader. And the perfect environment.
It still wont look "real" if your glass is just a plane with shell modifier, or a slim box.
This is why:





Model all that stuff and you should be good, if you think it's important for your renderings.

don't forget the low-e between the panes.

About the architectural glasses, I'd not recommend to use multiple solids for long rendertimes, even if is correct to thing in this way. I mean make vray follor the real life situations. But is useful, as a lot of peoples did in the past, to use a simple plane for glass in windows saw by the exterior with a IOR refraction value to 1,0001 to have not a problem o distorsion.
But is better always to test to get exactly what is needed. The above method of multiple boxes for windows glasses will give for sure the good blur to the reflections given by the multiple reflecting faces.

This tread is like those movies with terrible special effects....you keep watch them to see how bad they are.
..initially I thought this thread was part of a joke or something similar....mmmm fools' day is far away....or pranks for forums...maybe a Maxwell user trying to convert vray users to the other side.

I'm dizzy trying to find logical reasons...I'm going back to work!!!

I absolutely, completely and utterly disagree with this. If your glass (based on the settings earlier in the thread) is taking too long to render, you need to be looking at other reasons as to why. This setup is nonsense for anything other than when you receive a 3rd party model that has no thickness to glazing and you don't have time to sort out.

I said I'd say.. to tell that sometimes is better a workaround method to get same results in shorter times. But if u think to get the real effects or to replicate always the real life simulating the real phisics u will lost a huge amount of time. I say it because. I try always to avoid th faking solutions. Did u try to render 3 boxes with material settings that should be checked to get a good glass to say is not faster the old method of one plane? Believe me or not some users got in the past Excellent results even with standard material using vray reflections proper map. Then u can approach what u prefer. Try to put even 3 boxes (without spaces) together to simulate 3 layers of glass for example and watch if u will not need to try a solution with the between faces deleted , and i could tell some other examples that makes prefer some tricks to avoid too much reflections/refractions and get the same results. But for sure everyone is free to use his ideas and concepts...

[grantwarwick]

He was referring to render times, not the way in which you construct your glass and I agree with him.

If you are making physical sacrifices to a model to cut down render time then you simply don't understand what Vray is capable of and how you can target render time issues almost always very easily.

Ok I apologize for the mistake.

OMG
But better to leave space to the specialist like u, sorry if I told a so stupid thing .

Hate to be a thread digger but that's not a render but a photo :')
