UE4 Opera house Real time ray tracing

The work on the front hall of the opera house is about to be completed. I am testing the UE4.27NVRTXCaustics branch. So far, its performance is satisfactory to me, real-time ray tracing caustics, translucency, reflection, refraction, and shadows are amazing!

After enabling real-time ray tracing, RTX3090 can enable DLSS 60~70fps at a resolution of 2560X1440.
I used some megascans assets, such as books and flowers on the table.
