Hi! well I’ve faced a problem with translucent material reflections, they are basically really low-res and no options to improved have been found by me so far. Here how it looks, opacity = 1
This is essentially the best you can get with Lumen reflections on translucent surfaces in 5.0. It’s been improved in 5.1 if you can wait.
It’s possible to enable screenspace reflections in your material properties, but I don’t think it falls back to reflection captures for offscreen reflections.
