Architectural glass reflections

[Allypander]

Hi,

I've been working on this rendering for a few days and it's nearly there. I just cant get the reflections right in the glass panes.

Could anyone suggest why the panes have their own reflections, rather than a realistic overall reflection (not explaining myself very well but hopefully clear in the attached image). Most apparent in the foreground doors.

I'm using an HDRI background/environment.

 

Vray with 3d Max

Glass mat settings:

Refraction = Nearly white, IOR = 1.52

Reflection = full white with fresnel, gloss val = 1,

 

Cheers

double check if your glass has a thickness. if it is a single plane, without any volume it could create some "lens distortion effects" like you see. another thing you can do is to check is there is a smoothing problem on the surface. simply apply a smooth modifier and check "autosmooth" with the default values

Did you try "fall off" reflection instead of white and without fresnel?

Thanks for your suggestions guys.

I did try your recomendations, but to no avail.

I then played with the background settings, which (I think) is where the problem lay.

I have now changed the Vray reflection/env. to a bitmap rather than an HDRI image. I have manually offset the image tiling (U-axis) in the material editor to get a reasonable perspective. Unfortunately the reflections dont realistically relate to the lighting.

I realise this is a bit of a bodge job, but can just about get away with it in this case.
