Well, if it was really linear from 0 to 1 (0-100, 0-255) then we could use maps on it, right now, even with one more decimal, mapping roughness is hopeless. Even if the underlying property is really an exponential ramp, we pretend to use maps on it, so a 50% gray in a bitmap should always be 50% of said effect, from a visual standpoint, right?

True.
Didn't even think about maps before.
That should be the correct behaviour indeed.

And that's what we will try with the next release.

It is a beta software for crying out loud. It evolves. Users who need to render their old scenes can switch back to previous plugin version.
You're telling, that there will be no updates that fix old stuff?
Current behaviour of glossiness value is very limiting.
It doesn't have to be in 1-100 range. Could you maybe add just one more decimal place? At the moment the smallest number can be 0.001. Can you make it to be 0.0001?
That would give us 10 more glossiness steps and it would also keep the compatibility of previous scenes.
Any thoughts? Can it be done?

increase precision decimals in max preference from 3 to 5

Hah, never thought about that.
I'm used to do it from c/script code.
Thanks for the tip.

After playing about tonight after a year or so of not using Octane, this jumped out at me when trying to do a timber floor. 0.001 gave me what I'd expect to get at 0.95 or so in vray, so 0.05 in octane. To solve compatibility, just fix settings in scenes saved with older versions.
