* When enabled, translucent surfaces are rasterized again to create a minimal translucency GBuffer, using depth writes and tests to only capture the frontmost layer * Lumen Reflections are run on the translucency GBuffer, without denoising to reduce overhead (forced to mirror) * Finally the translucent base pass depth-tests against the frontmost layer depth and applies the high quality reflections. Subsequent layers continue to use the Radiance Cache based reflections. * Disabled by default due the constant overheads when any translucent surface is on-screen * New Post Process Volume and Project setting to enable #ROBOMERGE-AUTHOR: daniel.wright #ROBOMERGE-SOURCE: CL 19387917 via CL 19387985 #ROBOMERGE-BOT: UE5 (Release-Engine-Staging -> Main) (v926-19321884) [CL 19391295 by daniel wright in ue5-main branch]
