WIP - Glass advice please

Is that Dublin Ohio?

I would randomly select all those glass panels, and add 3 glass materials with different noise bumps. To randomly select groups of panels you might have to collapse them all to a same object first. Noise should be offset by using different phase times, and should show only slightly ie. black/white should be at 1-2 strenght, maybe it should even be gray/white.


It is important for your glass panels to be planar, and not twisty the same way the building is... having said this, i'm not really sure how to do id because the model seems like it's following the twisty form tightly, and you might end up getting two triangles / two planes instead of one.

Glass definitely needs something to reflect in order to look real, you might scatter a couple of clouds on one side, or even change the sky in the original image. The HDRI needs to suit the photo, or the manipulated thing if you change something, but it doesn't have to be the same thing.

I would reduce the refraction and change the interior to gray or something darker because it's way too bright inside. I actually find it that a fresnel IOR of 1.54 or whatever it is for glass, might as well be a little bit higher if you want to achieve a nice effect in archviz, you might as well go as high as 2.
But also, from what i see in your fresnel map, it's not really black, nor really white. You might want to keep black black, while dimming the white a tad.

cheers pailhead and all the rest very helpful stuff

Yeah all the glass is twisted (and will be in reality actually)
Was wondering just for simplicity if one could add a single bump-map
to all the glass to speed things up a bit but not sure what that bump map would look like. Tried once on another project and got some strange results...

Will try out a lot of this stuff on Monday when I am back on the proj so big thanks to everyone for the help

wow look mutch like twisting torso in Malmö Sveden

[tbny]

thats funny . I am from malmo!
I guess once you twist a tower
it will tend to look like another
tower thats twisted..

[ARK_3D_bureau]

yes thats right...
