BB about your posts.

You are accurately calculating what you expect from Poser, and afterwards you find that Poser has indeed performed that way. Which is good as such.

But in the meantime, you apply GC to the 5% reflectivity and 95% refractivity (100% together) while in my opinion you should not. Your blue reflects 33/128 = 26% while your red refracts 125/128 = 97.6% (113.6% together) and the ratio 5:95 now reads 26:97.6 so the reflection compared to the refraction in the result will appear five times stronger than nature will show. And when this ratio gets distorted, internal reflections will be done wrong too.

Throw in transparency for the glass to get decent shadows from a direct light, and complexity increases even more.

So in order to come close to photorealism using Firefly, balancing transparency, the raytracing nodes and GC is an "interesting one" to say the least. In my opinion that is.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
