Ray Trace is not rendering elements in reflections.Ray Trace is not casting light through colored glass that is off scene.
Reason:"Render All Objects" is not enabled in Ray Tracing settings.When disabled, only elements totally inside or partially inside will beincluded in rendering.Solution:1. From Menubar, go to Settings > Rendering > Raytracing.2. Enable "Render All Objects".Notes:This can effect elements outside the scene that may be seen inreflections of elements inside scene.
