- As others above said, make sure you enable Hardware Ray Tracing and make Lumen use it (you already do it but I am repeating it anyway for others just because it’s crucial):
- The console variable which will solve the reflection blurriness is: “r.Lumen.Reflections.Temporal 0” but it will come at expense of some noise, which will require increasing lumen reflection samples.
- If you do Jewelry design renders, just use Path Tracer. Use realtime renderer with lumen just as a preview, in the same way you use viewport in offline DCCs, and when you are rendering finals for client, switch to path tracer. It will be much better than just rasterizer with ray traced reflection pass.
- Set your Unreal Editor theme to something that doesn’t make others’ eyes bleed
