General Thunderbolt - UE5 Render Test (Lumen vs Pathtracer)

This issue took a bit longer to render, actually it was rendered twice, in different ways.
The official version of UE5 has been out for a while, so I thought I could start learning. Looked at foreign tutorials, adjusted the parameters of the lumen, but still feel that it is not as good as pathtracer, even with the addition of hardware light pursuit, the correctness of the light is still not very good. This point look at the back as well as the character's feet in the mirror can be found.

There are also rendering problems with the mapping of the character's face. This character's face mapping is split into two pieces, which rendered with black filigree. Similar models have been rendered in UE4 without this happening. If the problem persists in subsequent builds, I'll have to run back to UE4.
