decimals issue

[gueoct]

I am applying roughness to a specular material to make it frosted glass.

At Roughness 0,000 it´s clear

With one click it´s Roughness 0,001 and VERY rough

To achieve a slight roughness have to change my spinner decimals to 4 or even 5.

Is there a way to work with reasonable units?

There is not another way, sorry.

i wish octane units would, like max units, range from 0 to 100.
in octane units 1,0 is the highest value
it´s much quicker to deal with numbers above zero without comma...

+1
I would prefer linear system where 0 is none and 1 is 100% - like in iray. Its so much easier to tweak parameters.

There is not another way, sorry.

out of curiosty, can i ask why?

why can't you just map the roughness value to another arbitrary scale, like 1-100 or from 0 to 1, in a way that is useful??? (wouldn't this be similar to a gamma transformation?) right now, not only it's hard to really use roughness directly, but mapping roughness and other logarithmic parameters (parabolic, exponential, whatever the case) with a bitmap is useless as well...

when workling with centimeters or even meters, having decimals set to 0,0001 is super un-handy.
Is is not possible to have custom octane units?
