I thought I noticed something a while back, and it's definitely become a thing for me. I noticed it first on car headlight lenses during the beta...their reflection seemed VERY bright and I had to artificially knock them down and just keep moving. But I've looped back around and tested this out again and it seems odd.
What I made here is just a simple geosphere inside another geosphere to simulate a thin wall like glass, or lenses. The inner sphere's normals are flipped so that the outside points out, the inside points in.
Rendered on the left is Corona. If you notice on the bottom of the Corona render, there are two reflections of the single square light in the scene...the inside sphere, and the outer facing sphere.
On the right is a Vray render of the same scene with roughly the same material. No doubled up reflection, I'm assuming because the second reflection faces outward.
Did I miss a setting somewhere or is this a bug or is this physically correct? This cant be right...objects don't reflect an outer facing surface this way. Riiiiight? 8-)
Someone is not right here...the question is who.
