A&D Materials and Reflecivity

[fabw]

I have a big problem to set correct reflectivity for different materials I use in my interior like white lacquer on the kitchen locker, floor panels, white wall and so ...what about black colors?

 

Are there any rules to set this reflectivity correct?

Justin has a point. Conservation of energy helps of course and the right material as well but what your eyes see is not always what the numbers speak for. Always take some real world reference photos and compare your test renders to them. I do it all the time. Good luck.

Justin is correct... do what looks right. Spend 5 mins on google or go walk through a showroom and make notes on how the different materials are behaving under different lights.

If you want to get technical about it you can always use the refractive index chart.

I haven't figure out how to get it to work with A&D shader but I'm sure you can, I use the nk settings in Thea.

There must be away to use the IOR value or the BRDF.
