Possible Vray Glass Problem

[shauncarollo]

So I'm retouching some images from this past semester for my grad school app and I've come across a problem I forgot about during finals. If you see the attached:

 

 

The glass on the building looks like it's cut off towards the top of the image. Now the glass was created in Rhino, with an offset to give it thickness for real glass. I have upped my max depth, so I don't think it's a problem with that.

 

My question for you all is, when you model glass, you give it thickness correct? Or am I thinking of this wrong since Max is not a solids modeling program? Do you just use single planes/surfaces? Any finally, What can I do to remedy this?

 

Thanks!

I am absolutely confused about what you're confused about.

 

I don't see any cutoff, I see reflection of other building.

 

Solid modeling in CAD has nothing to do with thickness. There is place in 3D for both thick and thin glass surface, and Vray supports shading of both, difference being the thin will lack refraction and will simple be akin to "opaque mirror". In photoreal approach, thickness is always given true to reality.

I also think is reflection, this mean that what seems to be despairing glass is actually glass reflecting the sky instead of the surrounding buildings.

Other option could be hat you don't have top in those buildings, are they open at the top? if so, the glass is just showing that, only the sky in the front and sky in the back.

Now if there is a top mesh in your buildings, then check that VRay is rendering both sides of that ceiling, by default it does but sometime things move by itself right

I had thought that initially, but wanted to double check. If the masters say reflection, I will go with that! Thanks guys.
