Do not make elements n<1 invisible

[martinseyrich]

I work in X-ray optics, where the refractive index n is slightly smaller than 1.* This means for me convex lenses are defocusing and vice versa. The simulation can do it, however the glass elements become practically invisible when doing so. This hard to work with, and practically unusable for screenshots. Can you please add a setting to keep glass elements visible no matter what refractive index they are set to?

Best,

Martin

*No, n<1 does not violate Einstein. The trick is the difference between group and phase velocities.

If you set the background to white in settings -> more scene settings -> theme, glasses with refractive indices below 1 will have a black border without infill.

Thanks. I was looking for such a setting, somehow I missed it.
