Hi,
the same scene that works well on 5.1.1 (Windows 10) have big problems (black mesh without materials or bad materials and remain black not render start) to start Path Tracing on RTX 3090 and last NVIDIA drivers. Any1 with similar problems?

Project on UE 5.1.1 with last NVidia Drivers, HDRI backdrop plug-in

5.1.1
5.1.11920×1080 195 KB

The same project on UE 5.2 cloned from UE 5.2 from previous 5.1.1 project

5.2
5.21920×1080 69.7 KB

within UE 5.2 that not crash but become very slow…

No problems in ray tracing, the problem is only in path tracing mode, same machine (Dual Xeon 120 cores), with UE 5.2 reinstalled too…

A little late but run into this problem today. I had the exact same problem here when I updated a project to 5.2 from a previous engine version via the “Switch engine version”. What I ended up doing was to create a different project in 5.2 and migrated the contents from the previous one. So far it worked fine.
