Nd-number value precision

Hi again!

I'd like to have a more accurate precision to the Nd-number value when
you're creating transparent objects. More decimals to the Nd-number box
and that the render engine ofcourse take those into account during the
rendering. It would help :)

Examples of the length of what those would look like here..
- Agate, Moss 1.540
- Air 1.0002926
- Anatase 2.490
- Carbon Dioxide (gas) 1.000449
And so on.. you get the idea behind this :)

The complete list is unfortunately on this website (hehe..)

Thanks in advance!

So you think you will see any noticeable difference between 1.0001 nd and 1.001?

Hawk-eyes....

will you model a solid block with that IOR to simulate air in a room then?

Sure why not.. and thank you for your nice sarcastic comments. I get
the message.

didn't mean to be sarcastic, sorry if you got it that way.

can't find anything wrong in having more decimals in the nd number, seeing air and carbon dioxide in the list just made me think that there was a bit too much precision demanded here. i was just kidding though, no offence intended.
