Summary
Updates the
material-refractionexample to use a proper IOR value (1.0 / 1.33for water) instead of1.0.This is a follow-up to #8311 which fixed IOR/refractionIndex being ignored in materials. The fix revealed that the example was using
refractionIndex = 1.0, which produces no refraction (IOR ratio of 1.0 means light passes straight through without bending). The example previously appeared to work because the bug caused custom IOR values to be silently ignored, defaulting to glass-like refraction.
