Hi samp,
To be honest, I don't know what your talking about
:
So when VIZ 4 says that your created material will reflect 85% of the light, and you place an override material above that material, saying that reflection should be 0,5. In that case you would get 42,5% reflection (0,5 x 85%)
I just don't get it. What do you mean by 'when viz says it reflects 85%'? Do you mean the reflectance settings before you add an override?
Because as soon as you add an override, this previous value does not account for anymore.
In my thought an "override" gets rid of the 'underlaying' values.
Great thing of the override is that it reflects an amount of light that you setup indepently of the color of material.
If you don't setup an override material, it is f.e. not possible for a black floor to reflect a lot of light. While this is okay for a very flat/dull floor, it's not good for highly reflective black tiles in most hotels or commercial buildings.
If you're not sure about the override material, do check the viz4 users guide
