Hi guys. please i need a realistic glass for this design, the trouble is an a plastic inlay into a two glass surfaces, the plastic inlay is not transparent, but it seems like transparent; also the second surface darkens and this does not happen in real life. please any idea, i have not much experience yet. thanks.
Plastic inlay remains clear after moving???

The surface remaining transparent after inserting the opaque sheet is a mystery... Is there any overlap between glass & sheet?
Darker lower pane: Not sure if this is the issue, but try adjusting the rayepsilon setting in the kernal settings. However, it could also be that if your light source is above the table it would limit the scatter of the lower glass, resulting in darker edges - also in real life?
Best,
Seeker

The surface to be in the middle of the two glass surfaces should not be transparent, it really is a mystery. only appears when I enlarge considerably.
the settings you suggest I have not tried all the'll get it
thanks

did you try leaveing some space between the planes ( not letting them be in contact) ?
cheers,

yes I've already tried and does not work, unless the distance is much greater than the thickness of the surfaces

Are you happy to post the obj/scene?

Hi , did I you checked the fake shadow option ?
If that doesn't work , make your glass material , glossy, set index to minimum and maximum the values for reflection and roughness ... You have now a mirror like material .... Apply a fall off map to the opacity node and play with the options.
If that doesn't work stay with the glass material and erase all inside faces ....

Thanks at all, i've tried the fake shadow option and not obtain any change, the fall off map i've not tried yet.
i share the scene...

Hi,
i quickly put together a scene that hopefully represents what you're trying to do. I don't have a whole lot of time right now, so it's far from being pretty, but i think it shows the principle
The tabletop consists of two panes (6mm thickness) with a specular glass material applied, with another "plastic pane" in between. This one is around .76mm thick ( which is the thickness of the standard foil they use to matte glass in real life), and intersects with both glass panes (important, so it shows properly)!! You can make this plastic sheet either glossy or specular and give it some roughness to create a matte glass, that still has the reflective and specular properties of the glass surface (i added some objects and lights to illustrate that). You can also make it completely opaque to give it the effect you're looking for.
You might also want to look for tutorials on how to do liquids in a glass, kind of the same thing, there are a few around here.
Btw. if you're really planning to build this table: If you're not going for the added safety of a laminated glass, you could also have it made from varnished single pane safety glass, which might come in a bit cheaper. The foils sometimes are crazy expensive and there usually are standard colors for varnished panes that are priced reasonably.
Hope this helps..
Best,
Lukas
