Hi everybody.
I need help.

Where can I to find a list of material reflectivity in floats from 0.0 to 1.0 for more accurately settings? I found only several lists with values in IOR.
And the second question... How can I make materials with very low reflectivity like a semipolished granit, calcite or marble? The lowest reflection and roughness seting looks still overmuch glossy (my subjective view).

Thanks
With regards

Hi,

We currently have no IOR inputs for the specularity of a glossy material.
We will add this in future versions, you'll have to tune it manually for now.
It's interactive so you can see what you're doing pretty good.

Regarding the specularity, you should try it again with the upcoming 2.1 which has fixed in the glossy material.
