Refraction in reflection

[domovoynafany]

Hi to all! I have some troubles with reflection of my glass in the table.
You can see it here.

Is there a chance this is physically correct and that the glass does look like this when viewed from below? (just place your camera below it, facing up, and see if it looks like that)

[domovoynafany]

Hah.... no, it's not phisically correct. If check "caustic (slow)" in glass material - it will works, as I want.... BUT
VERY-VERY slow. My last render time was 7 hours. =( (3000 x 4000 px) Without caustic - 2,5 hours.

Does your glass have refraction glossiness other than 1.0? If so, can you set it to 1.0 and see how it will render?

[domovoynafany]

No, glossy = 1 and on glass and on table.

[romullus]

Is it possible for you to upload stripped scene (just the glass and the table) for inspection?

the more i look at this the more it looks like the one ontop isnt right. like the IOR or something. it feels like there should be more clear glass for the thickness thats demonstrated in the reflection. anyone else?

Yeah i share your assumption. There is something weird with that glass

Mere speculations without an example.
Normals OK?
Clean geo... No overlapping, no doubles?
How is it modeled? Fluid in glass have at least three techniques i know of that ppl use.

So yup, have fun solving ;)
