Black Glass

Despite having a blue sky the glass goes black no matter what...

The edges of the glass look extremely sharp?

Make sure there's a gap between ground and glass.

Aren't they lovely?

Phong seems to have some relevance to it...

the first entry has to be "why is my light not working in daylight?" (answer: the former is insignificantly bright. see also, "why is my fart not audible against thunder?")

sorry for derailing this thread a bit, just wanted to point out that new users would greatly benefit from such a FAQ

UPDATED: Latest bidir on bigger scale

some renders exposing it further

MCNR was increased to 100000

The problem remains the same on 1.1.18

If I enlarge the scene (cm become now dm) then the glass becomes more transparent which IMO is odd since a thicker glass should be less transparent...

I can see caustics, they just look like a fart compared with the mitchell netravali ehanced spots.

Normals seem busted on the last shots (triangulated top edge ?), check the geometry again !?

You mean the ground I guess... there's no phong in the glass material, right ?

But they are way bigger ifMLT is to be used, AFAIK there's no problem with geometry, It's modeled from a cylinder, with all the normals as they should be.

It is of some relevance to the glass if you add phong to it, it becomes darker
