Path tracing with some Metahumans is not working UE5

Hi, in UE5 stable release using path tracer with some metahumans (such as Vivian) in not working - path tracing seems not to converge, a lot of noise everywhere and no progress…any advice?
The issue seems to be connected to hair - disabling “Enable Simulation” in the groom asset soves the issue (but we loose the simulations…)
thank you!!


Same here. Did you find any solution?

Still the same issue in 5.0.3.

We are in 5.1 and still same issue. I have to “enable simulation” and then disable it in hair blueprint to make it work
