roughness

Little question.

The roughness channel have a slider very big .....there is a reference for the material like a IOR table.....

example....5000 like a satin metal....10000 like a chome?

Just take away two zeros dude, think of it as 100%.

That way you have similar to most 3d apps.

Chrome roughness 10000 (100% reflectivity)
50% roughness = 4980 (10000-40 x 0.5)
Lambert roughness 40 (0% reflectivity)

Hi,

The current demo does'nt support maps on the roughness channel.
this is fixed in the next demo version coming in a few days.

So 8bit maps goes like this
Black = 10'000
White = 40

?

i posted above, maps are not supported on the rougghness channel with the current DEMO version.\
i'll add support for it soon, along those lines yeah

I know roughness maps are not in the current demo
Will be nice to have these

sorry my ignorance, but..

Why must i subtract 40?

Because 40 is the lowest value in the range for that setting.
