same problem as your bottle. Currently the first raytraced hit shader for glass is too dark. hence why it doesn’t look right.

just for the heck of it I put a light into a raytraced pill bottle. i removed the interior faces of the bottle. it just half’s the refraction bounces without further impact and does not do the double refraction that would naturally occur on a “thick” (double layered) surface. The trace seems good, just the first hit is too dark.

issue resolves as soon as i switch to substrate. but raytraced refraction are same in the substrate causing issues.

right now, the values that I am using are:
Max. Primary Hit Events = 64;
Max. Secondary Hit Events = 64;
It only happens with ray-traced refraction. Only primary hit events are causing the problem; anything higher than 1 starts to darken the glass as I increase the primary hit events value.
