[REQ] Infinite exponent

[ior]

It would be nice to have real unblurred/unglossy surfaces using nk data.

Because even if you use a large exponent, highlights are always blurred a bit.

This would make a silver mirror really flat as it should.

Use a Specular material and set Transparent to 'false'.

He said: nk data

Valid point though, this upgrades the request to: specular materials to support nk data ?

The infinite exponent can be done by defining a maximum value for exponent and make that value the infinite were the intermediate points make a curve that tends to infinite (like a logarithmic (EDIT:exponential) scale or something).

I tested with MtI and the maximum exponent before stripes appear seems to be around 67100000 exponent value, and it is still blurred a bit or a lot, depending on the use.

EDIT: It seems there is already an exponential value as it says exponent, so were is the limit? why the stripes?
This value is exponential in what sense?

A nk data can describe a dielectric material such as water or gas. nk, dielectric function, ior/absorbance, are all the same physical thing (for instance, in Ocean, it's the same)

The most simple solution would be allowing the use of nk data in a medium, as refractive index and absorbance are easy to compute from nk values
