Maintaining Spec Energy on Mix Materials Tweet

[cashley]

I have a question about something I have not been able to figure out about Octane Mix materials. When I'm mixing SSS medium shaders that have no spec and glossy shaders that do have specular, how do I maintain the specular energy of my glossy material?

By mixing the two materials, the specular is diminished, so what is the formula to getting a proper specular intensity on a mixed material like that? An IOR of 1.5 for a plastic that is mixed with a Diffuse shader with no specular, so the result is a dimmed down spec.

Is there a formula or workflow to maintain spec energy on mix materials?

Thanks,

I'm also curious about this since I've wondered the same for quite some time +1

AFAIK there is no way to that I'm afraid. Maybe in post or photoshop by faking it .

I really hope someone can shed light on this. I'm trying to create physically plausible materials in Octane and not knowing how spec energy works with mix materials is making that difficult.
