Hi Chris,
The main male character (BP_Arend) is the parent of all the others.
BP_Eva is the main female character. They are both white.
BP_Elsa and BP_Anke are extra characters. They are black.
When working in editor mode, I switch off the “displacement” boolean in the blueprint of Arend, as it is impossible to work.
When rendering, I switch it on.
This switch enables subdivided skeletal meshes on all metahumans, they use displaced textures.
When displacement is “on”, BP_Arend and BP_Eva don’t use nanite, as we got some bugs and disappearing triangles [Content removed]
But, all the extra characters do use nanite (they’re further from the camera, and triangles drop when characters are close).
To be able to use nanite on metahumans, we separated the face-skin from the eyes. Nanite doesn’t like the transparent materials of the eyes, so we haven’t displaced or subdivided the eyes and teeth.
I subdivided the face(skin) and the body using textures in the skeletal mesh tools. These were my settings:

I’ve managed to extract a test project, which can be found here:
I tried to simulate as many of the same conditions as I have in my project
In /All/Game/Cinematics-Tests you will find the sequence “Test_RayTracing_RectLight”
It can be slow to work if you try to open it when the “displace” boolean is on in BP_Arend (/All/Game/MetaHumans/Arend) - now it’s on.
I’ve rendered using the PreviewRenders_v01 preset, which is also available in the project. I’ve done a test without it, and it gives the same results.
But I noticed something new, I switched all extra characters off but forgot to switch off BP_Arend, and the render wasn’t okay, but not really the same as the previous render with all characters on… There seems to be an improvement when there are fewer polygons in the scene (see the mouth).
Renders can be found here: “RayTracing_RectLight\Renders\no shot\Comparison”
But for the completeness of this thread, I’ll add them here. The file names should explain what you see.
