searching for translucent material settings

[Guido Duba]

Hi,

Can anybody help me in finding the settings for a glasslike material, used as balustrade or balcony fence. Actually it is twoo sheets of glass with a tranparent white foil glued inbetween. In Dutch there is a word for it, 'milkglass'. Which is what it should look like.

 

White, translucent,and just a tiny litle bit transparent. Working my way from the standard material Glass White-Translucent_Frosted I can't seem to get what I envision. In some lighting conditions, and with specific backgrounds it looks a bit like what I'm looking for;

but then in another view it is way too transparent ans I lose form. It gets way to inderterminable.

See attached renderings and project photos

I would start with the following:

100% transparency,

IOR of 1.6

Check the Allow Surface Roughness box

Roughness of .5 or so.

This all works a little better with the Path Tracer.  Make sure you model your glass a solid with two faces.

[Guido Duba]

Roy, thanks for replying!

I'm not sure where to check the Allow Surface Roughness box, I cannot find it anywhere?

Included a short run with the suggested modifications to Glass White-Translucent-Frosted, IOR up to 1.6 (from 1.35). With Pathtracer checked. Doesn't seem the right direction, or is it all the Surface Roughness?

The fence is anAutoCAD Solid.

On the transparency page under fresnel.  A attached a test material.  It probably works better with the Path Tracer.

which build do you use? Roy changed blurry transparancy to surface roughness at a certain point. I guess this is the same.

[Guido Duba]

Jan,

 

Thanks, I also guessed I may be needing to update, using build 271 now.

[Guido Duba]

So _i never did update since I started working with build 271.

How do I go about it? Just downloading and installing will I not lose any of my saved materials, plants, etc.?

[George Ioannidis]

You will not.

[Guido Duba]

...but if I see correctly, the latest stable build is 0271...

[Roy Hirshkowitz]

You don't need to update for this -- I just changed the name more recently.  It's called Blurry Transparency in your version.

Try the attached material and let me know. 

[Guido Duba]

Roy,

it took some days. now busy with another project, so I tries it out in another model.

In this view/ lighting the material-expression is satisfacory

 

In this one however, when the viewing angle is more perpendicular to the plane of the glass, it becomes black.

As in the one underneath; the first balconies in the left facade are allright, the ones further away get a dark side. In this one I tries 70% transparency and 1.8 IOR.

[Roy Hirshkowitz]

Try this one-- it reduces the transparency a little and adds some specular (Highlight Intensity at 1.00) reflection to supplement the fresnel reflectivity at glancing angles.  Use the Path Tracer.

Roy,

 

I didn't see no reply-button to your last post -so I post it here:

Used the NewFrostedGlass, but I think it is a downturn from your first material. I tried some mending with transparency etc. but to no avail..
