white paper

[waterthinking]

Hello

I am trying to emulate white matte paper and keep asking myself about the right settings, in particular for the specular channel.

My take so far (but might be very wrong):


GLOSSY MATERIAL

diffuse_0.9
specular_0.1
roughness_0.95
ior_1.3

Is this ok?

Thanks in advance

Yes, those are perfect.



















Just jk, I have no idea, but I don't think you will find a scientifically correct answer, even if Octane is pretty good in representing real life materials, it's still an approximation, so... As long as it looks good, it's ok, no?

My doubt fine-tuning the material furthermore is that specular relates very strongly to color, so that we should have a very high specularity for white, close to 1, then let a very high roughness (again, close to 1) take care of the absence of reflections for matte paper..

Any thoughts?

What evironment are you using? How are your gamma settings? It`s hard getting those right while maintaining the " white paper " look you want to achieve.

I am using an hdri as floatimage and with gamma set to 1. I am after a "studio" light
